Abstract: Analyses of plastic instabilities are reviewed, with focus on results in structural mechanics as well as continuum mechanics. First the basic theories for bifurcation and post-bifurcation behavior ...

Abstract: The possibility of localization of a buckling pattern is investigated for a class of structures in which the initial buckling mode is periodic. A simple model indicates that the basic mechanism ...

Abstract: In a numerical micromechanical study of the tensile properties of a metal reinforced by short whiskers, the elastic-plastic deformations of the metal are described in terms of crystalline ...

Abstract: A void in an infinite elastic-plastic material grows without bound when a cavitation stress limit is reached. Such unstable void expansion, driven by the elastic energy stored in the surrounding ...

Abstract: Process induced micro-scale evolutions can greatly influence the strength and resilience of a high temperature ceramic and intermetallic component. A micromechanical study, based on a unit cell ...
