Abstract: In this paper a theory of cylinder elastic-plastic formation in materials with difficult tension and compression modulus is presented. Based on elastic theory with different modulus in ...

This file type includes high resolution graphics and schematics when applicable. However, this relationship between stress and strain in a material is linear only when the force applied is within ...

ABSTRACT: The present study considers a finite element analysis of elastic-plastic axi-symmetric hemispherical contact for a frictionless deformable sphere pressed by a rigid flat. The material of the ...

The number of joints existing in the rock affects the elastic modulus of the rock, and the relationship has not been obtained. In this paper, 10 numerical models are established by numerical ...
