   Sammanfattning : Ductile fracture occurs in many situations of engineering relevance, for example metal cutting and crashworthiness applications, where the fracture process is important to understand and predict. Increased understanding can be gained by using multiscale modeling, where the effective response of the material is computed from microscale simulations on Statistical Volume Elements (SVEs) 1 containing explicit models for the nucleation and propagation of microscopic cracks.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Weak periodicity; Computational Homogenization; Crack propagation; XFEM;

   Sammanfattning : 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. LÄS MER
