- Abstract
- The mechanisms accounting for the failure of concrete under impart and impulsive loads, and the factors controlling the resistance of concrete to such loads, have been reviewed. It was found that little is known concerning the damage mechanism within concrete in response to dynamic loads. Apparently, the dynamic tensile strength of concrete has an important effect on its impart and impulsive resistances. A model based on the propagation of stress waves, which appears to give some insight to important material variables is described. Types of concrete which may merit evaluation for constructing structures subjected to dynamic loads are identified and discussed.
