A strain space description of an elastic isotropic, plastic orthotropic constitutive model is presented, which introduces the plastic orthotropy into the classical J2-theory by a transformation of the elastic strain deviator. The constitutive model is physically similar to Hill's model, to which it ...
Implementation of bounding surface model with zero elastic region under the continuum mechanic kinematic framework. • Thermodynamic analysis for the constitutive model of magneto-sensitive rubber. Abstract A three-dimensional visco-elastic-plastic constitutive model of isotropic magneto-sensitive (MS) rubbe...
The wave propagation in transversely isotropic elasto-plastic fluid-saturated porous media is in vestigated based on the dynamic constitutive model and the time-domain explicit finite element method giv en out in this paper , and calculating results are compared with those of elastic wave propagation...
-phase in Ti-6Al-4V15and aluminum alloys22. These microstructures cause a pronounced anisotropy,i.e. an orientation-dependent elastic as well as plastic deformation behavior. Furthermore, deformation mechanisms like deformation-twinning are sensitive to crystallographic orientation23. These findings were ...

An elastic plastic approach, modeling deformation of dense sand This thesis examines the mechanical behaviour of dense (dilative) sand. The dense sand was tested under high pressure conditions (80 MPa in one dimensional compression and a confining pressure of 7.2 MPa in triaxial testing) and high...
We introduce a simple approach to fitting interatomic potentials to represent elastically isotropic solids, in order to make direct comparisons with the predictions of isotropic linear elasticity. The potentials are of the Finnis-Sinclair type and are parametrized to fit Au and Ag. Under uniaxial loa...
The stiffness is typically characterized in terms of elastic constants derived from the low-strain linear response to applied stresses. On the other hand, solid specimens tend to show strongly nonlinear behavior at high strains, culminating in either yielding or catastrophic failure, so that there ...
The effective elastic behavior of laminates is well understood. In this contribution, we make use of the fact that the elastic homogenization can be extended relatively easy to the plastic case (He and Feng, 2012), which is interesting for bilayer metallic structures. With the aid of stress co...
