Abstract: Herein the concept of scaled memory (SM) is proposed to describe hysteretic material behaviors. SM scales the nonlinear variation of tangential modulus during monotonic loadings into a piecewise ...

Abstract: A viscoelastic model is proposed to describe the dynamic response of the saturated poroelastic materials that obey the Biot theory (1956). The viscoelastic model is defined from the velocity ...

Abstract: A constitutive model, based on the concept of scaled memory (SM), is presented to describe the undrained behavior of anisotropic clays subjected to generalized loadings. The SM capabilities that were previously established ...

Abstract: A constitutive model, based on the novel concept of scaled memory (SM), is presented to describe the hysteretic stress-strain response curves of soils during one-dimensional loadings. SM transforms the nonlinear plastic ...

Abstract: Experimental investigations indicate that the third stress invariant; Lode angle α affects significantly the behavior of pressure sensitive materials. The present communication presents a formulation ...

Abstract: Analytical solutions are presented for the diffuse and localized bifurcations of compressible solids subjected to plane-strain loadings. The solutions generalize the works for incompressible solids ...

Abstract: Using bounding surface plasticity, a constitutive equation is constructed to simulate the nonlinear behaviors of loose and dense sands subjected to various types of loadings. The critical state, which depends upon the ...

Abstract: A hypoplastic model is formulated to simulate the nonlinear and irreversible behavior of loose and dense sands. Hypoplasticity provides a theoretical framework that is simpler than elastoplasticity. The failure surface ...

Abstract: The elastoplastic Mohr‐Coulomb (MC) model is shown to overestimate the inclination of shear bands in granular materials. An extended Mohr‐Coulomb (EMC) model is proposed to get a more accurate analytical expression for the ...
