Transversely isotropic visco‐thermo‐elastic nanobeam with time harmonic laser pulse and new modified three phase lag Green‐Nagdhi model

Abstract

This investigation aims to examine the impact of the time-harmonic laser pulse on the vibration phenomenon in 2D homogeneous transversely isotropic homogeneous visco-thermoelastic nanobeam with a new modified three-phase lag Green Nagdhi (TPL-GN) model. The ends of the nanobeam are considered to be simply supported and held at a constant temperature. The mathematical model so formed is solved to derive the non-dimensional expressions for lateral deflection, axial displacement, temperature distribution, axial stress, and thermal moment. Effect of frequency and viscosity with new modified TPL GN heat transfer is represented graphically for lateral deflection, axial displacement, temperature distribution, axial stress, and thermal moment using the MATLAB software. Comparisons are made with the different theories of thermoelasticity and visco-thermoelasticity. Some particular cases are also deduced.

Size-dependent effect on the interaction of surface waves in micropolar thermoelastic medium with dual pore connectivity

“…Applying operator (1 − ε 2 ∇ 2 ) to equations ( 13)-( 19) and utilizing equations (20)- (22), we obtain the following (dropping the superscript…”

“…Several researchers [20,21] incorporated different thermoelasticity theories for the investigation of Rayleigh wave propagation in thermoelastic medium. Singh and his co-workers [22,23] studied thermo-mechanical interaction in different media subjected to different thermoelasticity theories. Thermo-mechanical characteristics of different composite materials have been investigated in several research articles [24,25].…”
