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 Greens 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.
