An improved interface cohesive zone model is
developed for the simulation of interface contact, under mixed-mode
loading. A new debonding initiation criterion and propagation of
debonding law, taking into account the pressure stress influence on
contact shear strength, is proposed. The model is implemented in a
finite-element program using subroutine VUINTER of ABAQUS Explicit.
An edge-notch four-point bending process and laminated vibration
damping steel sheet punch forming test are simulated with the
improved model in ABAQUS Explicit. The numerical predictions agree
satisfactorily with the corresponding experimental results.
