Mapping of Fatigue Damages - Program Shell of FE-Calculation
Original language description
The project described here is focused on multiaxial fatigue calculation in high cycle fatigue. The phenomenon of multiaxial fatigue, some basic assumptions and formulas are given first. Then the set of contemporary commercial fatigue postprocessors utilizing FE-data is reviewed in short. Since the postprocessors are aimed at commercial use, a possibility to use them for research is very limited. Therefore a PragTic software package, which is presented here, was developed. A set of experimental data (129experiments altogether) was compiled from references. Thanks to the PragTic software, they could be evaluated using 12 existing high cycle fatigue criteria. Fruitfulness of the individual criteria is commented and also the effects of phase shift and mean stress can be separately examined. These results serve as a basis for design of two new criteria. First of them is of integral nature, the second one is based on critical plane evaluation. The integral version demands great computationa
