高速衝突を受けるコンクリート板の局部破壊とその評価法

Abstract

In this article, local damage of a concrete member subjected to high-velocity impact by a rigid projectile and an evaluation method for the local damage were presented. Characteristics of the local damage of concrete were examined by conducting high-velocity impact tests. Considering the strain rate effects and pressure dependency of concrete, numerical simulations were conducted and the failure mechanism of the local damage of concrete was investigated. An evaluation procedure based on the failure mechanism was introduced and applicability of the procedure to previous test data was examined.
