Özet
A theoretical and numerical study of thermoelastic wave reflection from a rotating piezoelectric semiconductor half-space under transient heating due to a laser pulse and initial hydrostatic stress is introduced. The study considers a unified mathematical formulation considering the interplay among four main factors, namely: Eringen's non-local theory of elasticity that takes into account the size effect, Caputo fractional calculus that describes memory dependent behaviors, the Three-Phase-Lag heat conduction equation that includes finite speed thermal conduction, and the use of the Coriolis and centrifugal forces to describe rotation. Normal mode analysis provides four different wave modes which are called: Quasi-Longitudinal (QP), Quasi-Shear (QSV), QuasiThermal (QT) and Carrier/Plasma (CP). Numerical simulation for silicon suggests that the increase of the nonlocal parameter reduces the reflections related to QP and QT while enhances QSV and CP waves. Rotation leads to an increase in the transformation of mechanical energy into thermal energy by the effect of Coriolis force and the fractional order affects damping by the effect of memory. A Sobol global sensitivity analysis shows that the nonlocal parameter and initial hydrostatic stress have the most important effect (the total effect index is higher than 0.65), in addition to interaction effects between non-local scale and pre-stress, and between rotation and fractional order.
