Theory of Plasticity for Porous Metals

Theory for plasticity of face-centered cubic metals.

The activation of plastic deformation mechanisms determines the mechanical behavior of crystalline materials. However, the complexity of plastic deformation and the lack of a unified theory of plasticity have seriously limited the exploration of the full capacity of metals. Current efforts to design high-strength structural materials in terms of stacking fault energy have not significantly redu...

Porous and Foamed Amorphous Metals

This article reviews the state of the art in the field of porous amorphous metals by describing current processing techniques, mechanical properties, and potential applications. In addition to the reduction in density, the main benefit of introducing porosity in amorphous metals is the improvement in compressive ductility and energy absorption. This ductilizing effect is explained by: (1) shear...

Cyclic plasticity and fatigue of metals

Mathematical Modeling of Plasticity in Metals

We present a short introduction to continuum models for the plastic ow of metals. Our emphasis is on the physical principles underlying these models, the nature and validity of approximations involved, and the mathematical structure of the ow equations. Using the framework developed, we derive a simple, but realistic, model describing one-dimensional plastic ow. 1. Introduction When a piece of ...
