摘要
为了研究冲击荷载作用下无机玻璃材料的拉伸损伤特性,将适用于陶瓷材料率相关的TCK动态拉伸型本构模型加以改进,并将改进后的TCK本构模型应用于侧向撞击玻璃平板试验数值仿真.由仿真分析结果发现,改进的TCK本构模型对于无机玻璃材料的应力波传播速度、拉伸和压缩损伤区域的面积和位置,以及损伤扩展速度的计算分析较为准确.
The Taylor-Chen-Kuszmaul model,which is rate dependent and used to ceramic material,was modified and applied to glass materials so as to investigate the tensile damage characteristics of inorganic glass materials under impact loads.The modified TCK constitutive model was used to simulate the edge-on impact test of glass plate.Simulation results show that the modified TCK constitutive model can accurately simulate the propagation velocity of the stress wave,the size and location of the damage area,and the damage propagation velocity of glass materials.
