NOTE ON THE USE OF A SIMPLE TECHNIQUE FOR FAILURE PREDICTION USING RESISTANCE CURVES

The use of resistance curves in the prediction of catastrophic failure in a structure normally requires the determination of the point of tangency between the resistance curve and the applied stress intensity versus crack length curve evaluated for the failure stress. Since the failure stress is unknown a priori a number of interations or interpolations or both are necessary. This is often a cumbersome task. A simple procedure utilizing a transparency is presented which enables the critical stress intensity factor based on final crack length, the critical stress intensity factor based on initial crack length, and the failure stress to be found directly without iteration or interpolation.
