Abstract
The time response of surface displacement and acoustic impedance of in situ layers of articular cartilage were measured by using pulse-echo ultrasound. Disturbances were introduced by altering the osmotic pressure. Strongly nonlinear behavior was observed near physiological equilibrium. A model of articular cartilage is proposed which relates the results to cartilage microstructure.This publication has 8 references indexed in Scilit:
