Analyzing the outcome of centripetal and coriolis acceleration on a nonlocal thermoelastic material using the modified Green-Lindsay hypothesis

This study investigates the influence of rotation on a nonlocal thermoelastic material with temperature-dependent properties using the modified Green-Lindsay framework of generalized thermoelasticity. Exact analytical expressions for the displacement, stress, and temperature are obtained by employing the normal mode analysis without imposing simplifying assumptions on the field variables. Numerical computations are performed using MATLAB R2013a under appropriate boundary conditions. The results reveal that increasing the rotation parameter significantly alters the propagation and amplitude of thermoelastic waves, while the nonlocality parameter reduces the peak stress and temperature distributions by approximately 45% and 25%, respectively. Furthermore, variations in the empirical material coefficient produce noticeable changes in the displacement and stress responses, confirming its important role in the thermoelastic behavior of the medium. Compared with the corresponding reference model, the present temperature-dependent nonlocal formulation provides more realistic predictions of the coupled thermoelastic response, particularly in the presence of rotational effects. These findings are relevant to the design and analysis of advanced engineering materials used in aerospace structures, refractory components, and laser-assisted technologies.
