Definition

Crack initiation is the formation process of a crack, including the incubation period and the embryonic stage.

Theory and Application

Introduction

Fracture failure is one of the biggest threats to the structures in the engineering materials. The fracture process of materials consists of the crack initiation, crack propagation, and final parting. Apparently, the crack plays an important role in the fracture of materials. The cracks can be produced in the process of manufacturing, assembly, and service, which are the interaction results of the material microstructures, loading condition, and environment. Generally, the performance of structures would be adversely affected by the existence of cracks. For example, the cracks in the laser crystal would reduce its laser-induced damage threshold (LIDT), the cracks in the bearing structure are likely to shorten its service life, and the cracks on the optical surface would affect its...
