Most structural problems of interest to the aerospace community can be characterized by linear elastic fracture mechanics parameters because the extent of yielding is contained within a small region around the crack tip.
WebR6 and ETM formulations form the main ingredients; under small-scale yielding conditions (F≤F Y) the procedure follows modified R6 equations whereas in the fully plastic regime … WebJan 1, 1974 · Abstract Recent finite-element results by S.G. Larsson and A.J. Carlsson suggest a limited range of validity to the ‘small scale yielding approximation’, whereby small crack tip plastic zones are correlated in terms of the elastic stress intensity factor.
