摘要
It is shown that the dynamic boundary value problem and the heat conduction equation for simple piezoelectric materials with time-dependent properties result from the first and second law of thermodynamics. It is also shown that the conventional form of the heat conduction equation for geometrically nonlinear anisotropic thermoelastic media does not satisfy the principle of material frame indifference. A new form of the heat conduction equation is proposed.
