Abstract
The present research aims to study underwater shock wave propagation and attenuation in tissue models to understand mechanisms of tissue damages during shock wave therapies. In order to simulate interaction of shock waves with intercellular structures, thin porous layers of cotton immersed in water were exposed to underwater shock waves. Shock waves were generated by explosion of 10 mg silver azide pellets, which were ignited by irradiation of a pulsed Nd:YAG laser beam. Peak overpressures were measured with hydrophones at various stand-off distances. The motion of shock waves was quantitatively visualized by using double exposure holographic interferometry.
