Crash and statics simulation of short fiber reinforced thermoplastics in ESI Virtual Performance Solution taking into account manufacturing effects from injection moulding simulation tools. 2019-01-0715

Short fiber reinforced injected thermoplastics are widely used in the automotive industry in mass production. Prediction of the performance of short fiber reinforced thermoplastics by simulation for statics and crash simulation can be achieved by accounting for the full manufacturing process. The present contribution will present how micromechanics can be used efficiently inside ESI Virtual Performance Solution (VPS) to assess the performance of short fiber reinforced thermoplastics and SMC. To this end, local information about the material structure, fiber orientation, as predicted by a manufacturing process simulation, will be transferred and mapped automatically on the performance composite part model. The homogenization and mapping techniques will be presented for elastic and non linear application domains. In the subsequent analysis of the static and the crash performance, the impact of the manufacturing process and the resulting local variation of material properties will be analyzed and demonstrated through industrial applications.
