Existence of Periodic Solutions for the Quasi-Static Thermoelastic Thermistor Problem

We deal with a new model for the thermistor problem formulated as a coupled system of PDE’s involving nonlinear energy heat equation, stationary charge conservation equation of electrical current and thermoelastic equations of displacement. We establish the existence of weak periodic solutions rewriting our system as an abstract problem in order to utilize the maximal monotone mappings theory and a fixed point argument for a suitable operator equation.
