    Abstract

    A two-dimensional finite element program was developed to study the creep behaviour of bonded joints for two structural adhesives. The program used multiaxial viscoplasticity theory, and modelled creep by reducing the yield stress to zero. The necessary parameters for the finite element model were obtained from creep tests on beam specimens of the bulk adhesives. The results showed that creep led to a more even distribution of the stresses with the peak normal and shear stresses being reduced. However, the shear strain showed a large increase. The former effect could be beneficial in terms of joint strength, but the latter effect would be detrimental.
