| چکیده | ||
| This article develops a fractional-order Lord-Shulman (LS) generalized thermoelastic model to analyze a rotating hollow cylinder under plane strain. The cylinder, with traction-free surfaces, is subjected to non-uniform ramp-type heating on its outer boundary. Governing equations incorporating non-Fourier heat conduction are solved using the Laplace transform technique with numerical inversion. Results for temperature, displacement, stress, and dilatation are computed and graphically presented. The analysis demonstrates that both the fractional-order and ramp-time parameters significantly influence the thermoelastic response. Comparisons with classical Fourier-based theory highlight the model's accuracy in capturing wave propagation phenomena, providing critical insights for the design of structures experiencing sudden thermal loads. | ||
