“…The pulsed mechanical strength of materials significantly depends not only on such properties as the speed of sound, Young's modulus, static tensile strength, temperature, etc., but also on loading modes. It is known that when testing a material in different loading schemes in shock-wave [1][2][3][4][5][6] and dynamic [7][8][9] modes and also in tests for dynamic crack resistance [10,11], an increase in destructive loads is observed with a decrease in the duration of exposure and a delay in destruction.…”

The results of applications of various methods for measuring the parameters of high-speed loading using a strain gauge, a fiber Bragg grating located on a metal measuring rod and an interferometer monitoring the movement of the free boundary of the end of the rod are presented. Numerical simulation confirmed the adequacy of the description of the shock-wave process according to experimental data and showed that, with the thickness of the adhesive layer fixing the fiber Bragg grating and the strain gauge on a dimensional rod up to 100 µm, the deformation parameters of the sensors correspond to the parameters of the stress–strain state of the rod. Experimentally, a good correspondence of the results of measuring the magnitude of the relative deformation at a pulse duration of 10–100 µs using sensors of various types is shown, and an estimate of the limit values of the measured values of the deformation wave parameters is given.
