User-Defined Subroutine for Implementation of Special Finite Elements in ABAQUS for the Analysis of Adhesive Joints

Abstract

A user-defined subroutine has been developed to implement special 2-D and 3-D layered continuum elements in the commercial finite element program ABAQUS. These elements are specially configured to accurately predict interface stresses in adhesively bonded joints and are formulated using the hybrid stress technique to explicitly enforce stress equilibrium throughout the element domain and stress continuity conditions at layer interfaces. This report details the use of developed special 'adhesive elements' in ABAQUS for elastostatic analysis together with several numerical examples which demonstrate an improved accuracy and convergence behavior over conventional displacement-based elements. Sample input and output datasets and the complete FORTRAN subroutine which performs all element computations are presented in separate appendices.
