Abstract
In a common medical procedure known as shock-wave lithotripsy hypersonic
waves are generated and focused at the kidney stone. These shock
waves are thought to fragment the stone but also lead to injuries
of the kidney tissue. To predict and estimate this damage we develop
here a mechanical model for the response of soft tissue to the exposure
of shock waves. The material model combines shear induced finite
plasticity with irreversible volumetric expansion as induced, e.g.,
by cavitating bubbles. Dynamic effects like micro-inertia and rate
sensitivity are included. The time-discretized porous-viscoplastic
constitutive updates are described in a fully variational manner.
A finite element analysis localizes the damage in the human kidney
in good agreement to clinical and experimental studies.
