The present investigation is concerned with interaction due to expanding surface
loads in thermoporoelastic medium whose surface is subject to loads that suddenly emanate
from a point on the surface and expand radially at constant rate. The cases of loads shaped as
a ring and disc are considered in detail to show the utility of the approach. These loads are
chosen so that they exert a constant force on the surface as they expand. Laplace and Hankel
transform technique is used to solve the problem. The expressions for displacement
components, stress components, pore pressure and temperature change are obtained in the
transformed domain. To obtain the resulting quantities in the physical domain, a numerical
inversion technique is applied. Effect of porosity is shown on the resulting quantities. A
particular case of interest is also deduced from the present investigation.
