The method includes:
- load type dependent mean-stress correction (fiber direction and perpendicular tension / pressure and shear) using Haigh diagram,
- prediction of the degradation of elastic material properties and strengths per cycle,
- failure analysis per cycle based on degraded material properties using a 1st ply failure model (Puck),
- compact software integrated into Ansys environment.
This was a subtask of a project funded by the National Research, Development and Innovation Fund (NKFIH), Project title: “Production of polymer products by a short cycle time, automatized production technology for automotive applications, with exceptional focus on the complexity and recyclability of the composite parts”; The application ID number: NVKP_16-1-2016-0046.
