In recent years pavement maintenance planning has become a main task among highway agencies. In order to determine the structural capacity of a flexible pavement, non-destructive testing equipment is used. Many countries use the falling weight deflectometer (FWD). It is possible to obtain deflection data and backcalculate the pavements’ mechanical properties. However, the method used affects th...

In shear wave elastography, rotational speeds are converted to elasticity measures using elastodynamic theory. The method has a wide range of applications and is the gold standard for non-invasive liver fibrosis detection. However, observed dispersion in vivo human shows mismatch with purely elastic visco-elastic propagation laboratory phantom experiment we demonstrate that porosity fluid visco...

The importance of fibre reinforced plastics continually increases due to the excellent mechanical properties, low material and manufacturing costs combined with significant weight reduction. Today, components are usually designed and calculated numerically by using finite element methods (FEM) to avoid expensive laboratory tests. These programs are based on material models including material sp...

multi frequency vibrations of a system of two isotropic circular plates interconnected by a rolling visco-elastic layer that has nonlinear characteristics are considered. the system with two circular plates and interconnecting discrete continually distributed rolling visco nonlinear elastic rheological elements presents the model of hybrid nonlinear system. the analytical solutions of first asy...

In this work, we consider the problem of reconstructing a small anomaly in a viscoelastic medium from waveeld measurements. We choose Szabo's model to describe the viscoelastic properties of the medium. Expressing the ideal elastic eld without any viscous e ect in terms of the measured eld in a viscous medium, we generalize the imaging procedures, such as time reversal, Kirchho Imaging and Back...
