Two temperature theory of initially stressed electro-microstretch medium without energy dissipation.

The present study is attempted to analyze the thermoelastic interactions in a homogeneous isotropic electro-microstretch semi-space caused by mechanical source acting on the initially stressed surface. The problem is treated on the basis of two-temperature thermoelasticity without energy dissipation proposed by Youssef. Normal mode analysis is applied to derive the exact expressions for displacement components, force stresses, couple stress, microstress, conductive temperature, thermodynamic temperature and electric field. Numerical computations have been performed for magnesium crystal material to depict the response of mechanical source in the medium for thermally insulated boundary. Some comparisons have been made in figures to estimate the effects of two-temperature parameter and initial stress. [ABSTRACT FROM AUTHOR]
