Experimental and Numerical Study on the Dynamic Compressive Properties of Concrete
Abstract
Using electro-hydraulic servo-controlled testing system, the effects of strain rate on C30, C50 and C60 grade concrete are investigated in tests at the strain rates (10-5/s-10-1/s) in this paper. Based on the test results, the relationships between uniaxial compressive strength and strain rate are built, and the dynamic uniaxial compressive constitutive relationships of concrete are developed. Using the dynamic compressive constitutive relationship and Concrete damaged plasticity model in ABAQUS finite element program, the dynamic compressive properties of the three grades concrete are simulated, and the contrasts with test data are made.
