Forced vibrations of thermoelastic double porous microbeam subjected to a moving load

Rajneesh Kumar, Richa Vohra
The present paper deals with forced vibrations of a homogeneous, isotropic thermoelastic
double porous microbeam subjected to moving load, in context of Lord-Shulman theory
of thermoelasticity with one relaxation time. The Laplace transform has been applied to
obtain expressions for the axial displacement, lateral deflection, volume fraction field and
temperature distribution. A numerical inversion technique has been used to recover the
resulting quantities in the physical domain. Effects of velocity and time parameters are
shown graphically by plotting axial displacement, lateral deflection, volume fraction field
and temperature distribution against distance. Some particular cases are also deduced.
Keywords: double porosity, thermoelasticity, Lord-Shulman theory, microbeam, moving load
