1. Low-Cost Demonstrators : Enhancing Product Development with the Use of Physical Representations
Abstract : Ever since the early nineties and the advent of affordable and comprehensive 3D-CAD systems, companies have striven to take advantage of cost-effective Virtual Prototyping, gradually moving away from activities involving physical representations of the evolving product. There are, however, aspects of the product development process that are less suitable for virtual exploration. READ MORE

2. Dynamics of some vibro-impacting systems with amplitude constraints
Abstract : This thesis concerns the dynamics of some vibro-impacting systems with fixed or moving amplitude constraints. It is based on and includes five papers, marked A to E. Simple models of three different vibro-impacting systems with applications in the fields of impact hammers, granular flow and disk brakes in vehicles are analysed. READ MORE

3. Material modelling for simulation of heat treatment
Abstract : Heat treatment of materials is a fundamental metallurgical process. Materials are subjected to heat treatment to relieve internal stresses, reduce brittleness and to improve machinability. The properties of materials can also be altered such as hardness, strength, toughness, and wear resistance to suit particular applications. READ MORE

4. Simulation of welding and heat treatment : modelling and validation
Abstract : Many aerospace components with complex geometry are fabricated from smaller parts using joining techniques such as welding. Welding and the heat treatment which usually follows, can result in unwanted deformation and stresses. READ MORE

5. Improving availability of industrial products through data stream mining
Abstract : Products of high quality are of great interest for industrial companies. The quality of a product can be considered in terms of production cost, operating cost, safety and product availability, for example. Product availability is a function of maintainability and reliability. READ MORE
