Our FEM- investigations for the dimensioning of composite structures are done with the solvers included in NX and Nastran. Due to the vicinity of the production facilities and the engineering department a lot of feedback is given to the development. This leads to short and direct optimization process for adjustments in processing and material definitions. For the dimensioning and FEM-analysis the laminates are calculation and evaluated in layers using modern failure criteria. Very reliable results are achieved with the PUCK criterion. |
