Abstract
Electrically induced tissue damage is a coupled phenomenon in multiphysics. Conducting electricity produces heat and this increases the temperature. The soft tissue like skin, organs, brain, or muscles is burnt under successive heating. This damage is modeled by using a damage parameter with a corresponding evolution law above a threshold temperature. Electromagnetism, thermomechanics, and damage modeling creates a set of coupled and nonlinear field equations, by solving them with the aid of the finite element method, we compute a realistic example where the tissue absorbs the electric energy, converts to heat, and gets burnt due to the excessive temperature increase.
