Development of a Shell Element with Pressure Variation through the Thickness - Part 2

Abstract

A shell formulation was developed from a three dimensional solid. The shell element is isoparametric and has four corner nodes at which there are three independent displacements and three independent rotations. The element formulation includes both transverse shear and transverse normal deformations. The element utilizes reduced integration along the in-plane axes and full integration along the transverse axis. The formulation incorporates the Gurson constitutive model for void growth and plastic deformation. Hourglass mode control is provided by adding a small fraction of internal force determined through full integration along the in-plane axes and reduced integration along the transverse axis.
