Stress Intensity Factors for Cracking Metal Structures under Rapid Thermal Loading. Phase 1

Abstract

An SBIR Phase I feasibility study has been conducted on a novel method of calculating cracktip stress intensity factors for cracked metal structures under rapid thermal pulse loadings. The work couples a Green's function integration technique for transient thermal stresses with the well- known influence function approach for calculating stress intensity factors. A preliminary version of a computer program implementing the methodology designated AF-CRACK, was developed and delivered with the Phase I project report. Operable on an IBM-pc or compatible, the program demonstrates the ability to accurately calculate stress intensity factors, with very short turnaround times, and immediate graphics visualization of the results. Keywords: Stress Intensity Factors, Fracture Mechanics, Rapid Thermal Pulses, Crack Growth, Analysis.
