Abstract
Based on the extensive using spherical cavity expansion model in the penetration concrete subjected to projectile, with the Darwin-Pechnold constitutive model, taking Saenz uniaxial compression stress strain relationship instead of equivalent uniaxial stress-strain relationship of concrete,the orthogonal anisotropic cavity expansion model is developed by using Kupfe failure criterion to describe the mechanical behavior of concrete. The predicated model of penetration depth is in reasonable agreement with the experimental results. The model can reflect the real physical phe-nomenon of concrete material, so the use of spherical cavity expansion model is expanded and simplified in the problem of penetration.关键词
