An Application of Fracture Concepts to the Prediction of Critical Length of Fatigue Cracks. Part 1. A Review of Pertinent Aspects of Fracture - (Development of Relevant Concepts of Linear Elastic Fracture Mechanics)

Abstract

The purpose of this report is to synthesize technological concepts of fracture by making a historical review of the literature from 1913 up to the present time. The pertinent aspects of fracture and the development of relevant concepts of linear elastic fracture mechanics derivatives were delineated and summarized for the prediction of the critical length of fatigue cracks. The pertinent aspects of fracture consisted of the synthesis of Ingliss, Griffith, Orowan, Irwin, and Westergaard's relevant theoretical concepts. It also delineates Boyle's analytical and experimental results of the Westergaard-Irwin theoretical compliance of through-the-thickness centrally cracked plate and sheet for the determination of plane-strain and plane-stress fracture toughness stress-intensity parameter of high strength alloys.
