Small scale yielding criteria
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.

WebSometimes, the concept of contained yielding, as illustrated in Figure 2.2.5, is referred to as small scale yielding. 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. http://web.mit.edu/16.unified/www/SPRING/materials/Lectures/M5.3-Unified09.pdf

WebJan 1, 1979 · The deformation was followed from small-scale yielding into the fully plastic range. The objective was to provide insight as to the minimum specimen size limitations, relative to the characteristic crack-tip opening dimension J /σ o, necessary to assure a J -based dominance of the crack-tip region.
WebApr 1, 2007 · A theory of yielding and failure for homogeneous and isotropic materials is given. The theory is calibrated by two independent, measurable properties and from those it predicts possible failure for any given state of stress. It also differentiates between ductile yielding and brittle failure. The explicit ductile-brittle criterion depends not only upon the …
