The article presents a study of geometrically nonlinear progressive failure analysis of thin walled composite aerospace structures subjected to combined in-plane and out-of-plane loadings which are typically encountered in thin walled aerospace structures. Different ply and constituent based failure criteria and material property degradation schemes have been coded into a PCL code in Nastran, and progressive failure analyses of sample composite laminates with cut-outs are executed. Case studies are performed to study the effect of geometric nonlinearity on the first ply failure and progression of failure for laminated composite structures under combined in-plane and out-of-plane loadings.
