Transient disturbances in a nonlocal diffusive thermoelastic medium under modified Green-Lindsay theory

The present study analyzes the disturbances in a two-dimensional nonlocal diffusive thermoelastic medium whose surface is subjected to a thermal load under modified Green-Lindsay (MGL) theory of thermoelasticity. Normal mode analysis is used to obtain the exact expressions for the physical fields. Numerical results are computed for copper material and same have been illustrated graphically using MATLAB software. It is found that nonlocality, diffusion and time have significant impact on the considered physical fields and all thermoelastic disturbances are restricted to a bounded region. The study addresses the research gap in understanding the behavior of thermoelastic disturbances in a nonlocal diffusive material in context of modified Green-Lindsay theory when a thermal load is applied on the surface of the medium. Different theories of thermoelasticity are compared on the basis of the effects they have on field variables. Some particular cases of interest have also been discussed in the present work.
