Abstract

The authors discuss feasibility of acquisition of information on mechanical processes in geomaterials in post-limiting elastic deformation by variations in infrared radiation rate. Experimental recording of heat emission of rock salt and concrete samples in the limiting behavior of cyclical loading under uniaxial compression is described. Records of mechanical parameters appear qualitatively identical to heat emission variations which characterize the change in the stress–strain behave of the test geomaterials. The differences in the thermomechanical effects in concrete and rock salt in the described deformation mode are found.
