EXPERIMENTAL STUDY OF IMPACTOR MOTION IN A SANDY MEDIUM BY A CONTACTLESS METHOD

  • Published:
Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

Experimental data on the motion parameters of a steel spherical impactor whose diameter is 13.5 mm and which moves in a sandy medium at a velocity of 1470 m/s are presented. Induction sensors and the PIV (particle image velocimetry) method are used to record the impactor motion near a sandy obstacle and in a sandy medium, thereby allowing one to visualize a surface wave via high-speed video recording of the sand surface. The values of the parameters characterizing the impactor motion in the sandy medium and the surface wave propagation are obtained.
