A constitutive model coupled with distortional hardening for pressure-insensitive metals: Focus on the Cantor alloy
Source abstract
Abstract
The primary objective of this paper is to establish a dependable constitutive model for pressure-insensitive metals, with a particular emphasis on but not limited to the Cantor alloy. This model takes into account the effect of distortional hardening on deformation response of the material. It successfully establishes a quantitative relationship between the strength differential coefficient and the effective plastic strain. In order to acquire the distortional hardening parameters, the elastoplastic behavior of the Cantor alloy is determined through compressive, tensile, and shear tests. The comparison between DIC and finite element simulations confirms the accuracy of the proposed model in describing the deformation behavior of the Cantor alloy. The presented results and analyses offer a precise computational model for studying the deformation behavior of pressure-insensitive metals under various stress states. Additionally, this model can also be utilized for further research and analysis of the mechanical properties and performance of the Cantor alloy in practical applications.
