Heat conduction with “aging” memory

The term material with memory is generally used to indicate materials whose mechanical and/or thermodynamical behavior depends not only on the process at the present time but also on the history of the process itself. Crucial in heat conductors with memory is the heat relaxation function which models the thermal response of the material. The present study is concerned about a thermodynamical problem with memory “aging”; that is, we analyze the temperature evolution within a rigid heat conductor with memory whose relaxation function considers the aging of the material. In particular, we account for variations of the relaxation function due to a possible deterioration of the thermal response of the material related to its age.
