1. Experiments and modelling of fracture initiation at impact
Sammanfattning : The thesis addresses different questions, each necessary in the understanding of dynamic fracture initiation and crack propagation in steel. Emphasis lays on dynamic crack propagation experiments performed in the ductile to brittle transition region and possible conclusions, that can be drawn from them. LÄS MER
2. Dynamics Study of an Automobile Exhaust System
Sammanfattning : Low vibration levels are a critical objective in automobile exhaust system design. It is therefore important for design engineers to be able to predict, describe and assess the dynamics of various system design proposals during product development. LÄS MER
3. Sheet metal forming in the era of industry 4.0 : using data and simulations to improve understanding, predictability and performance
Sammanfattning : A major issue within automotive Sheet Metal Forming (SMF) concerns ensuring desired output product quality and consistent process performance. This is fueled by complex physical phenomena, process fluctuations and complicated parameter correlations governing the dynamics of the production processes. LÄS MER
4. A data-driven approach for Product-Service Systems design : Using data and simulation to understand the value of a new design concept
Sammanfattning : Global challenges such as increasingly competitive markets, low-cost competition, shorter lead time demands, and high quality/value output are transforming the business model of the company to focus beyond the performance requirements. In order to meet these challenges, companies are highly concerned with the customer perceived value, which is to connect the product with the customer in a better way and become more proactive to fulfil the customer needs, via function-oriented business models and Product-Service Systems.

5. Turbulence Modelling of Flows Related to Wall-Cooling Applications
Sammanfattning : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.
