Abstract
The dynamic caustic method is a power-ful tool to evaluate the dynamic stress intensity fac-tors. By means of the reflective type of this method,the dynamic fracture toughness about some mix de-signs for concrete under impact loading is deter-mined, and the contrast and influence of dynamicfracture toughness about the different mix designsfor concrete are compared and analyzed.
