New modelling approach by ARRK Engineering for composite development
Accurate prediction of delamination in composite materials is a challenge and often limits the application of lightweight materials in safety relevant components, as it may reduce the available strength significantly. In order to correctly evaluate delamination of composites while retaining a good runtime performance, a new modeling approach in LS-DYNA® was studied by ARRK Engineering using a full thermoplastic front bumper beam as demonstrator to perform a virtual vehicle evaluation.
Using a new modeling approach from ARRK Engineering, a full-vehicle simulation with TAFNEX™ CF-PP UD from Mitsui Chemicals has shown robust delamination prediction capability while still retaining high run time performance. Thus, the approach can be adopted in full-vehicle crash in order to evaluate composite delamination.
