The velocities of acoustoelastic waves expressed interms of Hencky (logarithmic) strain tensor
Velocities of the acoustoelastic waves in prestress contiuum were derived from the material model bassed on the Hencky logarithmic strain tensor. It was proved that the new material model and the derived formulas for wave velocities possess ...

Application of the logarithmic strain in acoustoelasticity
Expressions for velocities of elastic waves in pre-stressed solids are derived using the third order strain energy function and the Hencky´s logarithmic strain tensor as the measure of deformation....

Contrast enhancement of ultrasonic imaging of internal stresses in materials.
The ultrasonics methods, which detect applied or residual stress in materials, are based on nonlinear interaction of a small dynamic disturbance (acoustic waves) with the pre-formed state of the solid. This weak phenomenon (acoustoelasticity...

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 sensitivity of material parameters ...

Tangent moduli of the Green-Lagrange and left Hencky material descriptions derived from the stored energy function at finite strains
Tangent moduli associated with the linear logarithmic model of hyperaelasticity are derived. These moduli as functions of stress determine the speed of propagating acoustic waves....

Tangent moduli of the Hencky material model derived from the stored energy function at finite strains
Tangent moduli associated with the linear logarithmic model of hyperelasticity are derived. These relations are crucial not only to theoretical analyses but also to wave propagation and ultrasonic testing. The tangent moduli as functions of stress de...
