Abstract: A framework of the plastic-damage model with double scalar variables is established in nominal stress space under the small deformation assumption. In the damaged part, a damage tensor composed of double scalar variables ...

Abstract: The physical mechanism of the static–dynamic combined (S–DC) multiaxial strength of concrete is investigated considering cohesive and frictional strength. It is determined that the strain rate effects and stress state ...

Abstract: In this paper, the proposed yield function is the function of stress, hardening parameter, and strain rate. To fully describe the stress state and strain rate condition of material during dynamic loading, a new coordinate ...
