strain relations 
The experimental results indicate that the patterns of stressstrain relations are distinctly influenced by the initial shear stress in the cyclic singledirection shear tests.


In order to obtain the tensile stressstrain relations, a special fixture was used for the impact tensile specimen.


Furthermore, the axial stressaxial strain relations between laterally confined concrete under axial compression and multiaxial stressstrain relations for steel at constant high temperatures were studied.


This paper gives the stressstrain relations of the variational types on the basis of an assumption concerning the small deformation in the theory of elastoplasticity.


According to the theory of proportional loading in elastoplasticity, we simplify the complete stressstrain relations, which are given by the increment theory of elastoplasticity.


It is shown in a previous paper [4] that the stressstrain relations are the constraint conditions in all these variational principles, and cannot be removed by the method of linear Lagrange multiplier.


All these papers deal with the elastic body with linear stressstrain relations.


This paper discusses particularly variational principles and generalized variational principles for elastic body with nonlinear stressstrain relations.


Making use of this condition and the equations of steadystate motion, stressstrain relations and Hill anisotropic yield condition, we obtain the general solutions in both the cases of antiplane and inplane strain.


Hill anisotropic yield condition and unloading stressstrain relations, in this paper, we derive the general analytical expressions of anisotropic plastic stress fields at the slowly steady propagating tips of plane and antiplane strain.


Based on paper [1], the variational principle and generalized variational principle of elastic dynamics for elastic body with nonlinear stressstrain relations are introduced in this paper.


Hill anisotropic yield condition and stressstrain relations, we obtain the general solution of anisotropic plastic field at a rapidly propagating planestress cracktip.


The constrained HuWashizu principle, therefore, is proved to be equivalent with the HellingeReissner principle under the constraints of stressstrain relations.


By semiinverse method, the author has also proved that HuWashizu principle is actually a variational principle with only two kinds of independent variables, stressstrain relations are still its constraints.


Elastoplastic analysis based on the homogenization method is carried out to obtain the nonlinear average stressstrain relations of a porous material first.


Structural materials are assumed to be isotropic, with stressstrain relations being weakly concave.


In particular, it considers linearly viscoelastic solids and provides generalizations of the standard stressstrain relations of classical viscoelasticity.


Stressstrain relations in finite viscoelastoplasticity of rigidrod networks: applications to the Mullins effect


Adjustable parameters in the stressstrain relations are found by fitting experimental data on polycarbonate melt reinforced with short glass fibers and polystyrene solution.


Stressstrain relations are developed by using the laws of thermodynamics.
