中文摘要：

采用ABAQus／Explicit显式有限元分析软件对固支钢板带受大质量刚体亚临界速横向冲击进行了数值模拟．板带本构模型采用了考虑应变率和温度影响的JOHNSON—COOK模型，失效模式采用JOHNSON—COOK积累损伤的剪切失效模式．对弹性波的观测检验了模拟的可靠性．模拟结果观察到了冲击接触的不连续性和钢板带的惯性甩动伸长；颈缩拉损现象在冲击接触区边缘出现，刚体同时发生向跨中的滑移．对模拟结果的分析指出：冲击区附近钢板带塑性变形的外延传播以塑性强间断波的方式进行．

英文摘要：

By using ABAQUS/Explicit, an encastred steel belt impacted by a rigid mass with hypo - critical velocity is simulated. The ABAQUS inbuh material model proposed by Johnson and Cook wis used,which is suitable to solve the problem of impact and penetration. Asa result, the phenomena of contact discontinuity and inertial fling of the steel belt are observed. The reliability of this simulation is evaluated by surveying the elastic wave propagating through the steel belt impacted. Further analysis of the result data indicates that the deformation of the steel belt closely out of the contact region just behave in manner of plastic strong discontinuity wave.
