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 1^st 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.
