Abstract

This paper focuses on some of the recent developments implemented in the LUSAS finite element system. These developments include; a composite/laminated shell model formulated using a general multilayer semiloof shell element that permits arbitrary composite layups of isotropic, orthotropic, elastoplastic and concrete materials, backward Euler stress return algorithms for efficient elastoplastic analysis using the von Mises criterion, slideline procedures for modelling impact and large relative deformation between two or more surfaces of a structure, nonlinear thermal capabilities including the effects of phase changes and nonlinear radiative heat transfer, and a fully coupled thermo-mechanical functionality.
