A Viscoelastic-Viscoplastic Constitutive Model for Clay

A Damaging-viscoelastic-viscoplastic Constitutive Model for Human Vertebral Trabecular Bone Applied to Experimental Specimen Response

TION um damage mechanics (CDM) models, particularly when into finite element models, offer the potential for g the damage accumulation process and the risk of eal skeletal structures. For example, Zysset and Curnier ite general inviscid, isotropic damage model to cancellous the central assumption that plastic flow and damage n are intrinsically related [1]. With evidence from our [2] and others...

A Viscoelastic, Viscoplastic Model of Cortical Bone

Cortical bone, as the principal structural component of the human body, functions in both a load-bearing and protective capacity. As a material, cortical bone has been the subject of mechanical investigation and characterization for well over a century, and the time dependent nature of this material’s mechanical response to loading is well documented. To model this time-dependent behavior, many...

Simulation of long-term consolidation behavior of soft sensitive clay using an elasto-viscoplastic constitutive model

A Constitutive Model for Sands

In this paper, an elastoplastic constitutive model is presented for predicting sandy soil behavior under monotonic and cyclic loadings. The model is based on the CJS3 model that takes into account deviatoric and isotropic mechanisms of plasticity. The flow rule in deviatoric mechanism is non-associated and a kinematic hardening law controls the evolution of the &#10yield surface. In the present...
