Application of stress gradient plasticity model in different passivated problems

Tue, 2021-05-25 00:18 - Nayebi

In classical plasticity models, the physical length scale is not considered to control the size effects. Strain gradient plasticity models include one or more length scales that control size effects. Stress gradient plasticity model is introduced with a specific physical length scale and does not include any additional parameters.

New distortional yield surface model: Application in cyclic uniaxial and multiaxial loading: Rokhgire, Nayebi*, Chaboche

Mon, 2017-02-06 06:01 - Nayebi

This paper is concerned with the ratcheting prediction for steels. The yield surface evolution is integratedin the elastoplasticity analysis by a new proposed model. First, the new proposed model of DistortionalYield Surface (DYS) is developed and then ratcheting under different uniaxial and multiaxial cyclicloadings is investigated.
