A new method of studying the dynamic development of microcracks in hardened cement paste (HCP) plates subjected to dynamic load sources was developed by Avnon and Yankelevsky in 1991. This method is used to study the dynamic response of high‐strength‐concrete (HSC) two‐dimensional samples. The dynamic loading is produced by special cylindrical explosive charges containing about 10 mg PETN each. When initiated, these charges produce a dynamic pressure pulse for about 3 ms. The charges are…
