Numerical Modeling of an Elastic Spherical Contact under Combined Normal and Tangential Loading

Revue Nature et Technologie, 2023
The Contact between two surfaces with normal and tangential force involve friction dissipation phenomenon .The friction phenomenon can be formulated as a constitutive relation in a similar form to that of the elasto-plastic constitutive equation of ...

Extension of a multi-surface plasticity model to two-phase materials

International Journal of Solids and Structures, 2007
AbstractThe work reported in this paper is part of the ongoing research on the development of suitable elastic–plastic constitutive models for multiphase materials. This paper is concerned with the application of an elastic–plastic constitutive model based on the Mróz-multi-surface kinematic hardening rule to particulate metal matrix composites (PMMCs).

Application of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation [PDF]

Numerical Methods in Civil Engineering, 2014
In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship.
