Determination of cohesive zone model parameters for tape delamination based on tests and finite element simulations

Adhesive tapes are commonly used in electronics and automotive parts, and it is important to predict the peel force of the tapes by finite element simulations. Much research has been conducted to propose different functional forms of the cohesive zone model which are used in finite element simulations, but it is difficult to determine the parameters of those functional forms. In this study a methodology was proposed to determine the parameters of a bilinear cohesive zone model based on the results of the double cantilever beam test and several peel tests, and to predict the peel force at other peel tests by conducting finite element simulations. By comparing the estimated peel forces from finite element simulations to the measured peel forces, the methodology proposed in this study was proven to be simple yet effective.
