Abstract: A generalization of the area under the load-deflection curve method for estimating the J-integral in cracked elastic-plastic specimens in large scale yielding is proposed. The results of this ...

Abstract: A criterion for the generation of internal cracks normal to and astride the central axis in a drawing or extrusion process has been based on the conditions requiring less driving force with ...

Abstract: Three-dimensional finite element computations have been done to study the growth of initially spherical voids in periodic cubic arrays. The numerical method is based on finite strain theory and ...

Abstract: A new method of analysis of three-dimensional metal extrusion using asymptotic perturbation methods is presented in this paper. The plasticity model used depends on the first and second invariants ...

Abstract: This article reviews micromechanical models developed for fatigue cracking in fiber-reinforced metal matrix composites under mechanical and thermal loads. Emphasis is placed on the formulae and ...

Abstract: The general problems associated with the mechanics of forming processes are discussed. Particular topics include: (i) processing of electronic devices; (ii) flexible robotic systems; (iii) manufacturing ...

Abstract: Matrix cracking in ceramic matrix composites with fine grained fibers at high temperatures will be governed by fiber creep, as relaxation of the fibers eliminates crack tip shielding. Using a ...

Abstract: A test specimen capable of measuring the fracture resistance of bimaterial interfaces has been devised. A finite element approach has been used to characterize trends in the stress intensities ...

Abstract: This study presents a computational investigation of tensile behavior and, in particular, necking due to material inhomogeniety of cardiovascular stent struts under conditions of tensile loading. ...
