Material Data Determination and Crash Simulation of Fiber Reinforced Plastic Components

The quality of the mechanical simulation of reinforced thermoplastics depends on very com­ plex input parameters regarding the complex material behaviour. At the beginning of the sim­ ulation chain the material data has to be determined in different mechanical tests (tension, compression and shear, different fibre orientation to load direction, etc.). After the injection moulding simulation the calculated fibre orientation has to be mapped to the structural FE mesh. For the structural simulation a combination of the material model MAT108 and MAT54 was used to simulate the orthotropic, load case sensitive material behaviour.
