Abstract
Due to the occurrence of residual stresses during manufacturing, parts made of carbon fibre reinforced plastics exhibit considerable shape distortions. A finite element simulation tool to predict these distortions is developed in this work. All simulations are conducted using the finite element software LS-DYNA. For an L-profile, different finite element formulations are compared with regard to run time and accuracy. Having identical mesh topology, solid and thick shell elements show comparable run times and results. The layered composition of thick shells leads to a reduction of computational cost, but also increases the error concerning the predicted distortion angle. Finally, employing the insights gained from the mesh study, an actual car body part is studied for the purpose of validation.
