摘要

In this paper, a constitutive law for the description of the thermo-elastic compressible and incompressible porous solids has been presented. For compressible materials (J_(cp)~S = 0), the relation (8) takes on the form of the well-known law of Simo & Pister. For incompressible materials (J_(cp)~S = n_(0S)~S), the displacement curves, see right Fig., of the law in question are almost identical with the curves calculated with the finite law of Ehlers & Eipper developed for incompressible elastic porous solids without thermal effects.
