基于层裂机理的弹体侵彻混凝土的工程模型
Engineering model of projectile penetrating into concrete based on splitting mechanism
摘要
Abstract
Based on the theoretical resistance function from dynamic spherical cavity expansion model and the surface splitting mechanism,a prediction model was proposed for oblique penetration depth of rigid projectiles into concrete targets.In the proposed formula,the dimensionless coefficients denoting the projectile nose geometry were introduced to consider the variation of projectile nose geometry and the cratering depth.A prediction model for the deceleration-time history of the projectile with different nose geometries was obtained.The penetration depths and overload curve of the model were in good agreement with the test results.The research results can provide some help for the oblique penetration trajectory analysis and the design of the projectile head.关键词
