Determination of Constitutive Parameters of Crystalline Limestone Based on Improved RHT Model
Advances in Materials Science and Engineering, 2022 This study improves the RHT constitutive model based on some shortcomings, and the main improvements work are as follows: (1) hyperbolic function is used to make up for the deficiency of tensile strain rate enhancement factor of RHT constitutive model at

A non-monotonic constitutive model is not necessary to obtain shear banding phenomena in entangled polymer solutions [PDF]
, 2008 In 1975 Doi and Edwards predicted that entangled polymer melts and solutions can have a constitutive instability, signified by a decreasing stress for shear rates greater than the inverse of the reptation time.

Modelling the Triaxial Compression Behavior of Loess Using the Disturbed State Concept
Advances in Civil Engineering, 2021 This paper investigates the triaxial compression behaviour of Q3 loess soil and the construction of a constitutive model accounting for the structural effect of loess on the basis of the disturbed state concept.

Structure-based finite strain modelling of the human left ventricle in diastole [PDF]
, 2013 Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Constitutive model for plasticity in an amorphous polycarbonate [PDF]
, 2007 A constitutive model for describing the mechanical response of an amorphous glassy polycarbonate is proposed. The model is based on an isotropic elastic phase surrounded by an SO(3) continuum of plastic phases onto which the elastic phase can collapse ...

On the determination of constitutive parametersin a hyperelastic model for a soft tissue [PDF]
, 2018 The aim of this paper is to study a model of hyperelastic materials and itsapplications into soft tissue mechanics. In particular, we first determine an unbounded domain of the constitutive parameters of the model making our smoothstrain energy function ...

Universality of shear-banding instability and crystallization in sheared granular fluid [PDF]
, 2008 The linear stability analysis of an uniform shear flow of granular materials is revisited using several cases of a Navier-Stokes'-level constitutive model in which we incorporate the global equation of states for pressure and thermal conductivity (which ...

The creep behavior of simple structures with a stress range-dependent constitutive model [PDF]
, 2012 High temperature design remains an issue for many components in a variety of industries. Although finite element analysis for creep is now an accessible tool, most analyses outside the research domain use long standing and very simple constitutive models
