- •
A generalized heat-conduction equation which accounts for nonlocal, nonlinear,non-local, non-linear, and relaxation effects, is derived.
- •
The heat flux is supposed to be proportional to the gradient of the dynamical temperature.
- •
The material functions are allowed to depend on temperature.
- •
Several enhanced heat equations proposed recently in literature are obtained.
- •
Comparison is made with the heat equation of Thermomass Theory.
- •
It is pointed out that the heat flux is limited from above by a maximum value.
