Tóm tắt

A generalized thermoelastic theory, in the context of L-S theory, is used to investigate the two-temperature magneto-thermoelastic one-dimensional problem for a perfect conducting infinite medium whose surface is subjected to a thermal shock and is either considered as (i) traction-free or (ii) laid on a rigid foundation. The one-dimensional generalized magneto-thermoelastic coupled governing equations are written into a vector-matrix differential equation by using Laplace transform techniques and then solved by eigenvalue approach. The inversion of the transforms solution is carried out numerically in the space-time domain using Bellman method and illustrated graphically in two different cases. The effects of applied magnetic field and the twotemperature parameter on the field variables are studied.
