Abstract:

Based on the particle discrete element theory, five loading rates corresponding to different levels of strain rate were selected in this paper, and the corresponding loading rates were 0.001 m/s, 0.01 m/s, 0.1 m/s, 1.0 m/s and 3.0 m/s. The uniaxial compressive strength test of normal concrete (NC) and crumb rubber concrete (CRC) was simulated, and the effect of loading rate on the constitutive relation, crack propagation, meso-damage and energy evolution was systematically analyzed. The results show that the uniaxial compressive strength and the corresponding peak strain of the material present a nonlinear growth relationship with the increase of the loading rate. The loading rate sensitivity of CRC is more obvious than that of NC. There is a negative correlation between loading rate and NC crack generation rate, but a positive correlation between loading rate and CRC crack generation rate. The fitting equations between the mesoscopic damage variables and the loading rates of the two materials are proposed, and the fitting result is good, and the effects of different loading rates on the evolution law of elastic strain energy and kinetic energy of materials are analyzed.

Key words: road engineering, crumb rubber concrete, meso-damage, particle discrete element, loading rate, crack propagation
