Using of the Green-Lagrange-St.Venant Strain Tensor in Semi-analytical Deformation Analysis Method
The aim of this paper is to show how to introduce the Green-Lagrange-St.Venant strain tensor into a semi-analytical deformation analysis method. A static deformation analysis of the thick-walled closed anisotropic ...

Pitfalls in nonlinear elasticity.
Assumed linear dependence of 2nd Piola-Kirchhoff stress tensor on Green-Lagrange strain tensor leads to a paradox even in simplest case of one-dimonsional compression. Such an extension of Hooke s law to n...

The influence of the choice of a constitutive relation in the modelling of the wave propagation in pre-stressed medium
The most common constitutive relation in acoustoelasticity is the second-order constitutive relation expressed in terms of the Green-Lagrange strain tensor. This material model is characterized by the high sensitiv...
