The adjustment of targeted residual stress states is important in order to improve the properties of a component. Here, especially hot forming processes offer a meaningful potential since a number of parameters such as deformation state, temperature profile or cooling media can be adapted independently. This publication presents first simulation steps for the calculation of residual stresses on microscale...
A precise representation of the residual stresses, their development in numerical simulations as well as their interpretation in experimental results requires a profound knowledge of the thermal, mechanical as well as metallurgical properties of the considered material. This publication presents initial approaches for the calculation of residual stresses. For this purpose, the thermo‐mechanical behaviour...
Hot forming as a coupled thermo-mechanical process comprises of numerous material phenomena with a corresponding impact on the material behavior during and after the forming process. Within the subsequent heat treatment, possible rapid cooling of the hot formed parts leads to the diffusionless decomposition of austenite into martensite. In this context, in addition to the elastic, plastic and linear...
