In this paper experimental studies of ring-shaped reinforced concrete matrices for explosive stamping on deformation indexes under the eff ect of impulse loads are viewed. The study was carried out on sample, which was subjected to explosive loading. The results of calibration tests using the “Dynamics- 1” strain gauge complex are presented. The dependence of the tension in the matrix on the reaction of the strain gauge system is obtained. The obtained experimental data are compared with theoretical calculations. The general results of the studies obtained are given taking into account their further use for serial testing of matrices in order to determine their durability.
