Bulk Modulus

Abstract

Understanding and characterizing the mechanical response of soft biological tissues is a fundamental problem in biomechanics. Adequate models are needed to allow the study of both normal tissue function and the effects of disease and injury on these tissues. The mechanical behavior of biological materials is determined by their structure. The factors which control mechanical response include the gross (bulk) and microscopic tissue morphology, the chemical composition of the tissue, fluid flow in the tissue, directionality of tissue fibre structures, and the interfaces between various structures.

Modelling Radial Oscillations of a Bubble in a Spherical Liquid-Filled Elastic Solid

“…It is noted that the cavity volume is equal to the sum of the liquid and bubble volumes, where the volume of the transient bubble is and initially is , respectively then , (17) By combining ( 15), ( 16) and ( 17 where ( ) and is the initial radius of the cavity. We write as termed as the effect bulk modulus for the system, which increases with the bulk modulus of the liquid and the bulk modulus of the confinement where the bulk modulus is defined as the relative of the changing pressure by changing the volume (Arıtan, 2006). We substitute into (15).…”
