The software FEMFAT performs fatigue analyses in combination with widely used finite element programs such as NASTRAN, ABAQUS, ANSYS, I-DEAS, MEDINA, PATRAN, PRO/MECHANICA,..To ensure full and convenient integration into the customers\’ CAE processes, commonly used interfaces to multi-body, optimization and measurement systems are integrated as well (ADAMS, SIMPACK, TOSCA, RPC, LMS-TecMath, DIAdem). At an early stage of the design process – long before time and cost consuming tests are scheduled – FEMFAT provides engineers with reliable information on the fatigue life of structures. Therefore it is possible to improve critical points and most probably reduce the total weight, which results in high-level prototypes and consequently leads to less tests. The continuous practical usage of FEMFAT ensures its outstanding reliability. About...
