Shear wave velocity (Vs) is known as one of the fundamental material parameters which is useful in dynamic analysis. It is especially used to determine the dynamic shear modulus of the soil layers. Nowadays, several empirical equations have been presented to estimate the shear wave velocity based on the results from Standard Penetration Test (SPT) and soil type. Most of these equations result i...
PURPOSE: Current indices of risk evaluation for abdominal wall reconstruction focus on thickness and fat measurements, but do not address abdominal wall elasticity and texture assessment. Acoustic-Radiation-Forced-ImpulseShear-Wave-Velocity (ARFI-SWV) is a novel technology to assess skeletal muscle tissue characteristics. This technique has not assessed the abdominal wall physiology for reconst...

The attenuation of high pressure shock waves has been investigated. High purity copper, 6061-T6 aluminum, 6A1-4V and a phase titanium, an uranium alloy and two alloys of beryllium were examined experimentally at pressures as high as 3 megabars. Low pressure experiments were instrumented with a velocity laser interferometer. Intermediate pressures (to several hundred kilobars) were instrumented ...
