ABOUT THE DYNAMIC CONCRETE STRENGTH UNDER NON-UNIFORM PULSING COMPRESSION
Abstract and keywords
Abstract (English):
To determine the parameters of the concrete non-uniform compression dynamic diagrams the hypoth-esis of the constancy of the energy criterion of destruction of this material is used. An empirical relationship for finding the dynamic strength of concrete in non-uniform compression coefficient taking into account the time it is loaded to failure was suggested. For some heavy concrete classes specific parameters for that addiction are given. With the compiled calculation program a significant effect on the duration of the pulse parameters of the dynamic loading of concrete non-uniform compression diagrams was revealed. Some calculation results are presented in the article.

Keywords:
dynamic strength, impulse loading, non-uniform compression, energy fracture criterion, the concrete compression dynamic diagram, numerical experiment.
