Modeling of a homogeneous isotropic half space in the context of multi-phase lag coupled thermoelasticity

A two-dimensional multi-phase lag model in the context of generalized thermoelasticity is established for an isotropic half-space medium. vector-matrix differential equation obtained from governing equations using normal mode analysis. The eigenvalue approach applied to obtain solutions. temperature-dependent displacements, stresses, strains are calculated numerically and represented graphically show accuracy solution under mechanical thermal loads.
