Abstract:

Interlaminar stress characteristics within a bonded doubler model were evaluated. The study covered the inelastic range of the adhesive up to initiation of its visco-plastic flow. The analytical solution was derived by an iterative procedure, using a linear FEM program which follows a non-linear effective stress-strain relationship. This relationship was based on uniaxial test results of the bulk adhesive, which were found to correlate with corresponding in-situ characteristics of the adhesive. Author
