Thesis Title: Methodology for the Architecting of Time Dependent Complex Manufacturing Systems - An Engineering System Approach

Supervisors: Arlindo Silva (IST-UL), Elsa Henriques (IST-UL), Jorge Lino (FEUP), Juan Villarreal (Metalsa)

Thesis Abstract: The architecting of manufacturing systems is studied through the lens of the “engineering systems”, this research proposes a “holistic system architecting methodology (HSAM)” base on a systematic analysis and synthesis research methods (AD,Cladistics, DCC, DSM) oriented to manage the complexity associated with the design of changeable and evolvable assembly systems; the requirements from automotive industry demand a HASM able to guide the early design process to meet not only the short term demands for productivity and functionalities (cost, quality and efficiency) but also to provide the system with the required long term properties (“ilities”) in order to react to market externalities such as new product materials, wider product variety, fluctuations in demand and global production footprint; the proposed methodology is currently being validated through several case studies.

Thesis Topic: Polyurethanes (PU) are one of the most pervasive engineering plastics in our society, finding widespread applications. However, besides being petroleum based, one of the monomers for the PU production is highly toxic. This work aims to take existing efforts on renewable PU in a new direction, engineering hard blocks from protein biomass. A major scientific challenge is the high chemical diversity of the denatured crude protein, making control over the reactive pathway more difficult. The produced materials, in the form of coatings and bulk plastics, will be analyzed using a full range of thermal, chemical and mechanical characterization techniques.

Thesis Topic: Costumers and governments are pressuring companies to become more sustainable. However, the lack of research on how to incorporate and address these issues makes this a challenging task. This work aims to be a step forward into filling this gap and it is intended to do so in the following ways:

  • By contributing to the literature through the development of a decision support tool for the design and planning of closed-loop supply chains, based on multiobjective mathematical programming modelling. This contribution will arise in two ways. One is the development of a sustainable supply chain design and planning model with characteristics not yet addressed (e.g. sustainability itself, technology selection, intermodal transportation) or not simultaneously addressed in the literature. The other is the development of environmental and social indicators suitable for supply chain strategic decisions. While environmental assessment in supply chains has been showing some growth in the literature, few to none research exists in quantitatively assessing the social impact of supply chains in the context of design and planning.
  • By contributing with managerial insights for companies to be able to adjust or act proactively in light of already existing or potential sustainability policies.
  • By contributing to sustainable policy evaluation and definition by applying the developed methodology to real case-studies.

Research topic/area: Integration of Engineering, Manufacturing and Economic Issues in Design against Impact of Polymer Automotive Component

Research summary: The aim of this work lies on the development of an integrated approach that takes into account technical (or functional) and economic issues of injection molding plastic parts in order to support designers/engineers/analysts to decide faster and accurately (earlier on the product development process) among several design concept alternatives considering the main engineering aspects: manufacturing costs and functional performance (e.g. improved impact response). A combination of CAE analyses (injection molding flow simulations and structural analysis) enables the calculation of local mechanical properties, improving the mechanical performance prediction capabilities. In this way, engineering know-how in the form of design guidelines can be established relatively faster and more cost-effectively.

Thesis Topic: From time to time, new materials or processes emerge and lead to disruptive development cycles in terms of technology evolution. Over the last years, Carbon Nanotubes (CNTs) have been highlighted as the nanostructures that are almost performing the bridge between the materials and the devices. Still, it is not yet possible to find many devices able to take full advantage of the CNTs’ properties, mainly at mechanical, thermal and electric level. This research work intends to evaluate this bridge between CNTs as a material and CNTs-based devices through the production of a CNT-based functional transducer and its evaluation from an engineering systems perspective.

Thesis Topic: The ultimate aim of this thesis is the development of a joining technique using both adhesive bonding and friction stir welding. These joints would have good static and fatigue properties, and would be applicable in a large array of structure types (aircrafts primary and secondary structures, automotive structures, etc.). The use of these joints would allow more flexible structural design, lightweighting and high performance. A long with this goal this thesis also aims at instrumenting the developed joints for structural health monitoring.To fulfil these goals the following objectives have to be accomplished:

  • Development of a fabrication methodology for hybrid friction stir weldbonded joints, including designing
  • moulds and clamping systems, FSW tool geometries, procedures, etc.;
  • Characterization of the adhesive mechanical properties;
  • Selection of the correct process parameters for the fabrication of sound joints;
  • Mechanical characterization of the hybrid joints, including static mechanical testing, metallographic
  • analysis, and dynamic response properties assessment;
  • Finite element simulation of the developed joints;
  • Fatigue strength assessment of the developed joints;
  • Comparison between the developed joints and adhesive bonded joints and friction stir welded joints,
  • regarding all the studied properties;
  • Implementation of fibre Bragg grating (FBG) sensors for structural monitoring;
  • Strain monitoring using the embedded FBGs during manufacturing process.

It is expected that this thesis will be a significant contribution to the durability of lightweight stiffened structures, through the development and characterization of a novel joining technique, friction stir weldbonding. It is also foreseen that the implementation of sensing capabilities in the developed joints will improve the structural monitoring of safety critical structures. In order to achieve these aims, work and innovation in different but inter-related fields will be carried out:

  • Fabrication methodology for friction stir weldbonded joints will be developed;
  • Optimization through finite element analysis using a cohezive zone elements to model crack initiation
  • and propagation, as well as an experimental programme based on the Taguchi method;
  • Static mechanical testing will be performed, and the dynamic response of friction stir weldbonded joints
  • characterized through frequency response functions (natural frequencies and damping ratios), will be
  • measured;
  • A new technique to insert FBG sensors during the adhesive bonding curing process will be developed.

Measurements will be performed during the joining process in order to analyse the residual stresses induced by the manufacturing process, which is a novel result in itself. Using the pre-installed fibres, monitoring of the joint during the testing programme will also be possible. The failure initiation moment will be analysed;

  • Fatigue strength of the developed joints will be assessed through testing under constant amplitude loading;
  • Structural health monitoring during the fatigue strength testing using the embedded FBGs.

Research topic/area: Vehicles Reconfiguration: Enabling Fuel and CO2 emissions savings Through Modular Vehicle Designs

Research summary: Fuel consumption relates roughly linearly with CO2 emissions, travel demand (persons∙km) and transport demand (kg∙km). Given these dependencies, we conjecture about the convenience of a reconfigurable vehicle, enabled through modularity, to allow maximizing the vehicle’s load factor, on a per usage basis. The effect is that the coefficient correlating the fuel consumption with the travel demand and the transport demand varies according to the number of persons to be transported instead of being fixed according to the vehicle’s weight. This way, the impact of the mass of the vehicle regarding the fuel consumptions is shifted to lower levels.

Research topic/area: Hybrid Carbon Fibre/Metal laminates for high performance bolted joints in aeronautical applications

Research Summary:  Recent research applied to the space industry has shown that a significant increase in bearing resistance of composite bolted joints can be achieved by introducing metallic plies in place of the composite plies in the vicinity of the bolted area, or local hybridization carbon fiber/metallic laminate. This research is aimed at developing this bolted joint to an aeronautical application where it will have to solve new problems like fatigue, damage tolerance, reparability, and cost-effective design.

Thesis Title: Development and evaluation of an orthopedic absorbable implant based on chitosan

Supervisors: Alexandra Rodrigues (ISEL/IST-UL), Frederico Ferreira (IST-UL), Luís Pinto (Altakitin S.A.)

Thesis Abstract: The main medical applications of chitosan-based products include wound dressing sutures and tissue engineering scaffolds. However, the application of chitosan and its derivatives in 3D forms is very limited due to the inherent difficulties of the development process. The aim of this work is to produce and characterize 3D dense pieces based on chitosan to be used as (internal) bioabsorbable fixation devices. These products require the right strength and stiffness, which are necessary to allow the movement and comfort of the patient until the biological tissue is reconstructed. Additionally, they must be biocompatible, induce the bone formation and degrade over time. In this sense, experimental research work related with the optimization of the manufacturing process of the 3D chitosan pieces will be performed, involving its mechanical, microstructural and biological characterization.
