THERMAL STRESS ANALYSIS IN ROCKS WITH NONLINEAR PROPERTIES

Experiments have shown that the thermal-mechanical behaviour of rocks is temperature- and temperature-history-dependent. A method for stress analysis including material nonlinearity is developed, using the finite element method. Results of computation show that material nonlinearity, thermal constraints, rate of heating and cooling are significant factors in predicting thermal stresses, displacements and stability. The implication of these results on design considerations and safety measures in underground energy-related facilities is discussed. (Author/TRRL)
