湿饱和混凝土抗侵彻性能分析

混凝土侵彻弹靶相互作用是一种剧烈的动力学过程,但现有空腔膨胀模型用于混凝土侵彻工程计算时,引用的靶材料参数全为混凝土的静态力学特性参数,这必然会导致理论计算结果与工程实际的偏离.为提高混凝土侵彻工程计算预估精度,依据湿饱和混凝土的SHPB试验结果,在柱形空腔膨胀模型的基础上,考虑混凝土的动态响应特性,进行湿饱和混凝土侵彻深度工程计算,结果表明,其抗侵彻性能略优于正常状态.

The Analysis on Anti-penetration Performance of Moist Saturated Concrete

The interaction between concrete target and projectile is a violent dynamical process.When the exist cavity-expansion theory is used for penetration depth calculation,the referred target material parameters are all static mechanical performance parameters,this must cause the disagreement between calculation result and actual state.For enhancing the precision of the depth engineering calculation,the response characteristics of concrete were considered,and the performance of anti-penetration of water saturate...
