A new procedure for the identification of the delamination phenomena

A novel characterization tool for identification of full cohesive laws is introduced. Cohesive zones, with associated traction separation laws, are most commonly used either to describe or to simulate delamination phenomena. Our tool is based on the Global Digital Image Correlation, in which the kinematic space is defined. After summarizing the principle of the method, we focus on its validation and then on its behavior with noisy input data. This validation is numerically made (i) by building a set of images using an advanced simulation tool, and (ii) by identifying, from theses images, interface behavior characteristics. First successful results already show the effectivity of the proposed method and its robustness.
