A Crack Growth Rate Conversion Module: Theory, Development, User Guide and Examples Yu Chee Tong, Weiping Hu and David Mongru Air Vehicles Division Defence Science and Technology Organisation DSTO-TR-2050 ABSTRACT The use of crack growth analysis tools based on plasiticty-induced crack closure model, such as FASTRAN, CGAP and AFGROW, requires the conversion of crack growth rate versus the nominal stress intensity range curves to a "single" curve of crack growth rate versus the effective stress intensity range. In order to minimise the error arising from crack growth rate conversion and judicially utilise these software tools, a user-friendly tool was integrated into CGAP. This report documents the theory, implementation, the user guide and examples of the crack growth rate conversion software module. RELEASE LIMITATION Approved for public release
