Hardness as a tool for the estimation of the microstructural threshold
Abstract As it was described by K. Miller, fatigue resistance can be characterized by the existence of a microstructural and a mechanical threshold. The microstructural threshold is strictly related to the intrinsic microstructural properties of the ...

On the opportunities of problem- and process-adapted shear cutting simulations for effective process design
Abstract Due to the lack of generality for the accurate prediction of material separation, the finite element simulation is not well-established for shear cutting processes. Usually, the detailed material-specific behavior is determined in...
