Abstract: The endochronic constitutive equations developed previously by the writers for the description of sand behavior in true triaxial tests are applied to predict the behavior of Ottawa sand with a circular stress path in the ...

Abstract: The endochronic theory of plasticity is applied to discuss the cyclic full-reversed torsional loading of a solid bar with circular cross section. Numerical techniques are employed to obtain the ...

Abstract: The endochronic constitutive equation is written in differential form, which is then used to describe the deviatoric behavior of drained sand in true triaxial test. Explicit equations have been derived. The modified concept ...
