提出了夹层玻璃在冲击载荷作用下的破坏准则。该准则的主要思想是，在失效发生之前，必须在有限区域上达到临界能量阈值。然后，裂纹萌生和扩展基于局部朗肯（最大应力）准则。该准则在显式有限元求解器中实现。为了验证该准则的准确性，对夹层玻璃的平面和曲面试件进行了大量的实验研究。对于所有实验，进行有限元模拟。实测结果与仿真结果的比较表明，该判据具有良好的效果。(C)2010爱思唯尔有限公司版权所有。
A failure criterion for laminated glass in case of impact is presented. The main idea of this criterion is that a critical energy threshold must be reached over a finite region before failure can occur. Afterwards crack initiation and growth is based on a local Rankine (maximum stress) criterion. The criterion was implemented in an explicit finite element solver. Different strategies for modeling laminated glass are also discussed.To calibrate the criterion and evaluate its accuracy, a wide range of experiments with plane and curved specimens of laminated glass were done. For all experiments finite element simulations were performed. The comparison between measured and simulated results shows that the criterion works very well. (C) 2010 Elsevier Ltd.
