TL;DR: In this paper, a model describing layer-thickness-dependent radiation hardening in multilayers was developed by extending the Friedel model to take into account the layer thickness and the He bubble spacing.

TL;DR: In this paper, the effects of addition of different types of sands of different contents on the strain hardening behavior of hybrid fiber composites are evaluated. And the authors found that the addition of sand adversely affected the tensile strain hardness and multiple cracking behaviour of hybrid fibre composites.

TL;DR: In this paper, the phenomenological continuum plasticity models considering the unusual plastic behavior of magnesium alloy sheet were developed for a finite element analysis, and a hardening law based on two-surface model was further extended to consider the general stress-strain response of metal sheets including Bauschinger effect, transient behavior and unusual asymmetry.

TL;DR: In this paper, the modified Chaboche type combined isotropic-kinematic hardening law was formulated to account for the Bauschinger and transient behavior in automotive sheet forming.

TL;DR: The ratio of flow stress at a high temperature to that at O°C has been measured for polycrystalline Al and Cu, and for single crystals of Al the flow stress decreases ratio strongly with temperature above a certain critical temperature (about 250°C).
Abstract: The ratio of the flow stress at a high temperature to that at O°C has been measured for polycrystalline Al and Cu, and for single crystals of Al In Al the flow stress decreases ratio strongly with temperature above a certain critica1 temperature (about 250°C) In Cu a similar but more gradual decrease in the flow stress ratio is observed The results are interpreted in terms of a model based on sessile vacancy jogs in screw dislocations, which has also been used by Hirsch (1960) and Mott (1960) to explain linear hardening Below a certain critical temperature the screw dislocations advance with the aid of stress leaving a dipole or a row of vacancies behind; in this region the flow stress will be nearly temperature independent Above the critical temperature the jogs advance with the aid of thermal activation, vacancies being emitted by and moving away from the jogs in the same thermally activated process, and the flow stress decreases strongly with temperature The activation energy for this pr
