Abstract

Abstract

Determining of penetration deceleration on rigid-body by low-pass filtering of the measured penetration deceleration data is investigated. The concept of critical filter cut-off frequency is proposed. Critical filter cut-off frequency is acquired, penetration deceleration on rigid-body is determined. The penetration deceleration on rigid-body determined by the method presented in this paper shows a good agreement with calculation results of semi-empirical method based on cavity-expansion theory.
