The effects of the crack interaction on the fracture evolution of multi-cracked finite plates in plane strain loading conditions are considered. A modified crack length control scheme is presented in order to analyse such problems depending on one or more independent parameters. The aim is to provide information about a discontinuous response, such as snap-back instability, which can be only highlighted by a deformation controlled process. With reference to finite plates with one or more rows of evenly spaced collinear cracks, the snap-back branches of the load vs. displacement curve are numerically captured by means of a procedure based on the Boundary Element Method.

Abstract
The effects of the crack interaction on the fracture evolution of multi-cracked finite plates in plane strain loading conditions are considered. A modified crack length control scheme is presented in order to analyse such problems depending on one or more independent parameters. The aim is to provide information about a discontinuous response, such as snap-back instability, which can be only highlighted by a deformation controlled process. With reference to finite plates with one or more rows of evenly spaced collinear cracks, the snap-back branches of the load vs. displacement curve are numerically captured by means of a procedure based on the Boundary Element Method.
