1. Prediction of springback in sheet metal forming
Sammanfattning : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the stresses in the workpiece after the forming stage. LÄS MER
2. Prediction of springback in sheet metal forming: with emphasis on material modeling
Sammanfattning : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the residual stresses in the work piece after the forming stage. LÄS MER
3. On constitutive modelling in metal plasticity
Sammanfattning : .... LÄS MER
4. Analysis and modelling of plastic bending processes
Sammanfattning : It is well known that anisotropic properties of material allect forming of sheet metals and that non-homogeneous deformation across thickness of a bend gives rise to residual stresses. The interaction between material and process parameters determines, in a very complex manner, the formability of material. LÄS MER
5. Plastic behaviour of steel : experimental investigation and modelling
Sammanfattning : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. LÄS MER
