根据玻璃及胶层材料的物理特性,将塑性绞线理论引入到三阶段模型中,提出了一种计算夹胶玻璃后破坏强度的方法,并运用该方法研究了不同设计参数对夹胶玻璃后破坏强度大小的影响.结果表明:夹胶玻璃板后破坏强度随着玻璃的胶材厚度增加而增加,随着玻璃板长度的增加而减小;框支式夹胶玻璃板比点支式夹胶玻璃板具有更高的后破坏强度.
In this paper, a novel method to determine the post breakage strength of laminated glass was proposed based on the three stage model by incorporating the yield line theory. The influences of different design parameters on the post breakage strength of laminated glass were analyzed using the proposed meth- od. The results show that the glass thickness, supporting conditions, interlayer thickness, length of glass plate have a great influence on the post breakage strength of laminated glass.
