 This paper examines the effect of heat waves on a piezoelectric material when it is subjected to electromechanical loads. The paper looks at the effects of heat waves on the thermomechanical behavior of a flexible rod using a modified Lord-Schulman model with the concept of a memory-dependent derivative, MDD. The paper finds that the distribution of physical fields and the dynamic behavior of the electric potential are weakened as the inhomogeneity index increases. This article was authored by R.
