User-Defined Subroutine for Implementation of Higher-Order Shell Element in ABAQU

Abstract

A user-defined subroutine has been developed to implement a higher- order three-node facet shell finite element in the commercial finite element program ABAQUS. The element, designated HOT3, is based on a (1,2)-order plate theory specifically formulated to model thin and thick composite laminates and exhibits improved accuracy compared to conventional shear-deformable shell finite elements. This report describes the use of HOT3 in ABAQUS for static and vibration analyses by presenting the required element input data together with numerical examples. Sample input and output datasets and the complete FORTRAN subroutine which performs all computations for the HOT3 element are included.
