Abstract
AbstractThe traditional rheological method is supplemented by a new element—rigid contact, which serves to take into account different resistance of a material to tension and compression. A rigid contact describes mechanical properties of an ideal granular material involving rigid particles for an uniaxial stress state. Combining it with elastic, plastic, and viscous elements, one can construct rheological models of different complexity.KeywordsVariational InequalityGranular MaterialPlastic HingeConstitutive RelationshipMetal FoamThese keywords were added by machine and not by the authors.
