Data on the history of body deceleration in a rheological medium as a basis for verification of computational problems

Abstract

Relying on data on the history of body deceleration during high-speed penetration into the target, the paper reviews the Proceedings of the 23rd – 31st International Symposiums on Ballistics, as well as the findings in the field of terminal ballistics, i.e. the study of body acting on a target, and the history of striker deceleration in the target material. The paper observes a half-century path of development of the technology as a new scientific direction, started in the department of High-Precision Airborne Devices at Bauman Moscow State Technical University. Strikers in measuring technology are equipped with shock accelerometers and original electrical recorder communication systems. Theoretical and experimental studies revealed a new law of medium penetration resistance. The law allows the use of engineering methods to solve problems, e.g. spatial problems of penetration. The data on the history of the measuring striker deceleration recorded in the experiments provided additional opportunities for verifying the models and the results of virtual simulation of the processes of spatial penetration. The paper introduces the studies carried out by the authors in a wide range of different initial conditions of impact and designs of strikers and targets. New technical solutions in measuring technology developed recently are also presented.
