Macro slip theory of plasticity for polycrystalline solids

Macro slip theory of plasticity for polycrystalline solids A macro slip theory is presented in this paper. Four independent slip systems are proposed for polycrystalline solids. Each slip system consists of a slip plane which lies on a face of the octahedron in stress space and a slip direction which is coincident with shear stress acting on the same face of the octahedron. It is proved that for proportional loading, present results are identical with the classical flow theory of plasticity. For nonproportional loading, the macro slip theory shows good predicting ability. The calculated results are in good agreement with the experimental data. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Mechanica Sinica Springer Journals

Abstract

A macro slip theory is presented in this paper. Four independent slip systems are proposed for polycrystalline solids. Each slip system consists of a slip plane which lies on a face of the octahedron in stress space and a slip direction which is coincident with shear stress acting on the same face of the octahedron. It is proved that for proportional loading, present results are identical with the classical flow theory of plasticity. For nonproportional loading, the macro slip theory shows good predicting ability. The calculated results are in good agreement with the experimental data.
