1. Introduction

Crack, It is the break without complete separation of the parts. Crack is one of the

structural damage of the material or any objects. Most high strength metals and high

strength alloys under some plastic deformation in regions of high stress concentration and

fracture precipitated by a crack. It is also called the plastic deformation of the material. The

cracks are only created when the material have take attained over the ultimate load or

stress, pressure, tension exerted on the
