1. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

3. Theoretical experiment of GISSMO failure model for Advanced High Strength Steel
University essay from Högskolan Väst/Avdelningen för produktionssystem (PS)Abstract : When developing an electric vehicle, it is essential to evaluate the deformation in and around the battery box for different crash scenarios, and it is necessary to develop a more advanced model that would take into account all the stress modes. Thanks to the excellent properties of Advanced High Strength Steel (AHSS) combine with high strength for more safety and weight reduction for less exhaust emission, AHSS is more and more commonly used in automobile industry.

4. Micromechanical study of PFZ in aluminum alloys
University essay from KTH/Hållfasthetslära (Inst.)Abstract : There are a number of experiments showing that the ductility of aluminum alloys decreases during age-hardening heat treatment. Observing the grains of age-hardened aluminum alloys at the micron scale, one can notice that there are precipitate-free zones (PFZs) along the grain boundaries. READ MORE

5. Finite element modeling of straightening of thin-walled seamless tubes of austenitic stainless steel
University essay from Högskolan Dalarna/MaterialteknikAbstract : During this thesis work a coupled thermo-mechanical finite element model (FEM) was builtto simulate hot rolling in the blooming mill at Sandvik Materials Technology (SMT) inSandviken. The blooming mill is the first in a long line of processes that continuously or ingotcast ingots are subjected to before becoming finished products. READ MORE
