FIELD: material engineering.
SUBSTANCE: invention relates to the study of the strength properties of materials. Essence: the impact on the sample of the tested material is carried out by a shock wave created by the explosion of the charge. To conduct the test, a foundation is installed, on which a matrix base is installed, on which the test sample is placed, on both sides of which a radial grid is applied, on which a water tank is installed, in which an explosive charge immersed in a tank with water is installed at a certain elevation from the sample with the help of slats. To create a shock wave, a non-contact charge explosion is produced, and the residual plastic deformation is estimated by a radial grid applied on both sides. The device contains a foundation on which a matrix base is installed, on which the test sample is installed, on both sides of which a radial grid is applied, on which a water tank is installed, in which an explosive charge is placed on rails immersed in a tank with water and connected to a detonator.
EFFECT: possibility of testing structural materials under dynamic influence on samples of full-scale dimensions, as well as the ability to evaluate both the behavior of structural materials separately and as part of the structure in thicknesses up to 100 mm.
