A concept for scaling J R-curves by plastic constraint factors
Source abstract
Abstract
Ductile tearing resistance can be characterized in a physically meaningful way by the energy dissipation rate, R. The respective R(Δa)-curves can be re-evaluated from experimental JR-curves, and the latter can in reverse be obtained from the former by integration. For fully yielded specimens the geometry dependence of R(Δa)-curves can be scaled by plastic limit-load factors. This normalization opens a possibility for transferring a JR-curve from one specimen geometry to another.
