36. Computational homogenisation and solution strategies for phase-field fracture
Sammanfattning : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. LÄS MER
37. Rate effects at quasi-static loading on fracture toughness of structural steels
Sammanfattning : .... LÄS MER
38. Modeling of structural integrity of aged low alloy steels using non-local mechanics
Sammanfattning : Ageing of low alloy steels affects the structural integrity assessment as it most commonly causes embrittlement and a hardening of the material. This is due to theevolution of the microstructure during operation in the specific application. LÄS MER
39. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions
Sammanfattning : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. LÄS MER
40. Prediction of hardening, localization and fracture of multiphase microstructure in boron alloyed steel
Sammanfattning : Over recent years the demand of press hardened ultra-high strength steel for safety structures in automobiles has increased and continuation of this trend is expected.Components with tailored material properties can be manufactured using a thermo-mechanical process with heated and cooled areas in a tool.
