Recently, by detecting the drop of inflating pressure, the cavitation rheology technique has been developed to measure the local shear modulus of soft materials. In this article, we analytically extend our study on the cavitation problem to soft graded elastic solids. The mechanical property of the...

We introduce laser cavitation rheology (LCR) as a minimally-invasive optical method to characterize mechanical properties within the interior of biological and synthetic aqueous soft materials at high strain-rates. We utilized time-resolved photography to measure cavitation bubble dynamics generated by the...
Unbounded growth of cavity in soft solids subjected to internal pressure is a commonly observed phenomenon. Such phenomenon has been harnessed by developing cavitation rheology technique (CR) to investigate the local mechanical properties of many complex soft materials. The elasticity of...
Cavitation rheologyRelaxationThick-walled spherical shellClosed form analytical solutions for the dynamic expansion of a spherical void in a finite, spherically symmetric, nonlinearly viscoelastic medium are presented. We account for finite strains and application of load, both internally, at the cavity ...
