heal.abstract	Results from true triaxial cyclic tests on concrete are presented and compared with corresponding ones for dense rocks (mainly marbles) obtained under the same laboratory conditions. Common basic characteristics are confirmed regarding the essential effect of intermediate stress, the cataclastic mode of deformation under low confinement, the coupling between volumetric strain and deviatoric stress, the dependence of the equivalent modulus Eq and the hysteresis loops. Common characteristics are also revealed in meridian and deviatoric sections of peak strength surfaces, moreover a stress invariant and its work conjugate plastic strain increment are approximately equal. Concrete behavior is different on the postpeak plastic contraction under high confinement, on the creep rate, on the validity of the condition of convexity and on the considerable degree of violation of the condition of normality. A simple empirical equation is proposed and experimentally verified for predicting deviatoric sections of strength surfaces. © 1987.	en
