Abstract
The authors discuss capabilities of taking information on mechanical processes in geomaterials under post-limiting elastic deformation based on variation in IR radiation intensity. Experimental results on recording of heat emission from specimens of rock salt exposed to cyclic loading by uniaxial compression are reported. It is concluded that thermomechanical effects are useful in recording of onset of failure activation in geomaterials under cyclic loading.
