Abstract
Nonlinear global load and displacement behaviour of metals is not exclusively associated with yielding of material. It can arise in the case of material damage by nonselfsimilar crack growth whereby the influence of the plastic deformation is negligible. The process of yielding and crack growth are inherently interwoven such that their individual effects cannot be readily separated either experimentally and/or analytically. This has led to frequent misinterpretation of the observed data on material behaviour. Unless the combined influence of loading rate, specimen size and material properties are understood, little progress can be made to translate small specimen data to the design of larger size structural components.
