Simple evaluation method of adhesive failure criterion in multiaxial stress states by uniaxial tensile tests

We propose a simple tensile test with which to identify the parameters that constitute the failure criterion of an adhesive in a multiaxial stress state. In this paper, we define the failure criterion as the proportional limit of load-displacement curves obtained from experiments. We first introduce...

description	We propose a simple tensile test with which to identify the parameters that constitute the failure criterion of an adhesive in a multiaxial stress state. In this paper, we define the failure criterion as the proportional limit of load-displacement curves obtained from experiments. We first introduced the failure criterion based on the first invariant of the stress tensor and the second invariant of the deviatoric stress tensor. To determine the unknown parameters of the failure criterion, two experiments were performed. The first was a tensile shear test for bonded plate structures to obtain the strength of the adhesive material in simple shear deformation and assess how the strength depends on the strain rate and adhesion layer thickness.
