1. On computational homogenization of gradient crystal inelasticity
Sammanfattning : Crystal inelasticity is the main modeling technique employed to study the mechanical behavior of polycrystalline metallic materials. This class of models has the capability to represent micromechanical phenomena such as plastic slip, grain boundary interactions, and dislocation pile-up. LÄS MER
2. On computational modeling of sintering based on homogenization
Sammanfattning : Liquid-phase sintering is the process where a precompacted powder, “green body”, is heatedto the point where (a part of) the solid material melts, and the specimen shrinks while keeping(almost) net shape. In the case of hardmetal, the microstructure is defined by WC-Co-particleswith large pores, whereby molten Co represents the liquid phase. LÄS MER
3. Numerical Model Reduction and Error Control for Computational Homogenization of Transient Problems
Sammanfattning : Multiscale modeling is a class of methods useful for numerical simulation of mechanics, in particular, when the microstructure of a material is of importance. The main advantage is the ability to capture the overall response, and, at the same time, account for processes and structures on the underlying fine scales. LÄS MER
4. On Homogenization of Stokes Flow in Porous Media
Sammanfattning : .... LÄS MER
5. Micromechanical modeling using computational homogenization
Sammanfattning : This thesis addresses micromechanical modeling of materials using computational homogenization. On this topic, theoretical and computational issues are discussed, and numerical investigations of different material systems are performed. LÄS MER
