Abstract

Finite Element programs are offering today lots of different element types and solutions sequences. To find the proper combination for a given investigation, an evaluation has to be done. To safe weight and cost during production, modern parts out of composites will be designed more and more to their ultimate limits. Sometimes stress could occur which can not anymore predicted properly with the standard methods. Based on an isotropic angle under tension, different element types and solution sequences as well as different mesh refinement in MD Nastran were compared. An analytical solution was used to evaluate the proper method. In a final step, a layered part was calculated and the results projected to composite parts.
