An approach to calculate the J-integral by digital image correlation displacement field measurement

Abstract:

This paper presents a combined experimental-numerical technique for the calculation of the J-integral as an area integral in cracked specimens. The proposed technique is based on full-field measurement using digital image correlation (DIC) and the finite element method. The J-integral is probably the most generalised and widely used parameter to quantify the fracture behaviour of both elastic and elastoplastic materials. The proposed technique has the advantage that it does not require crack ...
