How to optimize cohesive zone failure parameters in peel test in Abaqus?

14 January 2020 1 7K Report

I am doing cohesive zone modeling in abaqus. I am trying to find out vales of 'E/Enn', 'nominal stress normal only mode', and 'normal mode fracture energy' by peel test.

You can't find these values from peel tests! you have to conduct bulk specimens tests.

Peel tests give you the value of GIC.
