Investigation of heavy-duty concrete samples behavior under shock-wave compression

The article presents the results of experimental and theoretical investigations of the mechanical behavior of heavy concrete specimens subjected to shock-wave compression. A microsecond plane shock pulse was generated by an explosive lens in the experiments. This resulted in the experimental free surface velocity profiles for specimens ranging in length from 25 to 500 mm. The dynamic compressive strength of the heavy concrete specimens and the dynamic hardening coefficient were determined. Numerical modeling was used to investigate the effects of shock wave propagation in a model concrete specimen, represented by a heterogeneous medium with a stochastic distribution of filler particles. The results of numerical modeling of the mechanical behavior of concrete under impact loading revealed the formation of non-stationary and significantly inhomogeneous deformation fields with the development of dissipative structures at the mesoscale level.
