1. Failure of thinwalled structures under impact loading
Abstract : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. READ MORE

2. Failure of thin-walled structures under impact loading
Abstract : Increase in computational power during recent years contributed to a significant development in numerical methods in mechanics. There are many methods developed that address various complex problems, yet modelling of initiation and propagation of failure in thin-walled structures requires further development. READ MORE

3. On computational homogenization of fracturing continua
Abstract : Ductile fracture is important to control in many industrial processes, be it a desired phenomenon (e.g. in metal cutting) or a failure to be prevented (e.g. READ MORE

4. The role of microstructure for crack propagation in cortical bone
Abstract : Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. READ MORE

5. On efficient modelling of progressive damage in composite laminates using an equivalent single-layer approach
Abstract : In order to reduce the weight and subsequently the fuel consumption of their vehicles, the automotive industry is currently very active in research to incorporate laminated composites of Carbon Fibre Reinforced Plastics (CFRP) into structural components. This effort is a reaction to the increasing demands from regulatory bodies aimed at reducing the CO2 emissions from the transportation sector. READ MORE
