TL;DR: In this article, the authors developed a fully rate-dependent constitutive law for cohesive interface elements considering both, the strain rate dependency of the initiation stress and the strain ratio dependency of fracture toughness.

TL;DR: In this article, a finite element model of a T-joint subjected to six different loading configurations is calibrated with the six different parameter sets, based on the available experimental data, recommendations are given for the type of test to choose for calibration of rate dependent strength parameters.

TL;DR: In this article, two methods to improve the accuracy of the stiffness of cohesive zone models of rectangular adhesive layers are proposed, which use existing closed-form solutions for rectangular elastic layers between rigid plates.

TL;DR: In this article, a concept for stress-based fatigue life prediction with associated experimental parameter identification of adhesively bonded joints using hyperplastic adhesives under multiaxial stress conditions is presented.

TL;DR: In this article, a polyurethane adhesive is considered as an exemplary material and subjected to tensile, compressive and shear tests, and a new hyperelastic model is coupled with linear viscoelasticity to account for the strain rate dependence observed for the tested material.
