Abstract: The constitutive framework presented accounts for the coupling between the damage process and the plastic deformation process. The model build its basis on the thermodynamic equivalence of an actual damaged continuum and ...

Abstract: An analysis of test system misalignment is presented for the creep test. Sheet type rectangular 1100-0 aluminum specimens are used for discussion. It is found that the creep strain at the ...

Abstract: Two sets of experiments with and without strain cycling have been carried out to test the validity of an equation derived from the improved theory of endochronic plasticity. It has been found ...

Abstract: Many experimenters fail to appreciate the significance of test system alignment during a tensile test. Poor alignment can increase data scatter and significantly influence some of the test ...

Abstract: The stress response to various axial-torsional strain paths is discussed. The modified endochronic plasticity theory, which is formulated based on plastic-strain is used for theoretical analysis. ...

Abstract: A set of strain-controlled experiments has been performed on tubular specimens of annealed stainless steel. The strain-paths are designed to highlight the characteristics of path-dependence in the ...

Abstract: Creep of metals has been investigated by means of the endochronic constitutive equation. This is a unified approach. Transient creep tests have been conducted on 304 stainless-steel specimens ...

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 ...
