Sect VIII Div 2 Part 5 Elastic Plastic Local Failure
(OP)
Does anyone know the derivation of equation 5.6 for the limiting strain shown at 5.3.3.1.c? It looks like a variation on the triaxiality treatments I've seen from time to time. I googled a bit and found a paper by Deng, et al that uses it to evaluate some pressure vessle materials, but they dont give the derivation. IS this a curve fitting exercise?
