Non-linear dynamics analysis of multilayer composite shells with enhanced solid-shell elements

Abstract

This paper presents the non linear dynamic response of multilayer composites with an enhanced solid-shell element. The transverse shear and transverse normal locking are treated using the Assumed Natural Strain formulation (ANS). For the enhanced part, one, three and five parameters are examined. Comparisons of numerical results with those extracted from literature show the good performance of the developed formulation in the isotropic case. The three enhancement choices give the same results in the multilayer composite case.
