Abstract In order to study the dynamic response characteristics and anti-deformation ability of different architectural glass under the action of gas explosion, four types of architectural glass, namely tempered glass, laminated glass, hollow glass and float glass, were selected as test samples. The explosion test is carried out by changing the thickness of the glass specimen, the gas concentration and the explosion venting material and other factors under the condition of fixed support on four sides. The results show that different types of architectural glass have different anti-explosion capabilities, so the failure mode and crack distribution under the action of gas explosion are different. With the increase of the thickness of the structure layer, the anti-explosion ability of different building glasses is improved. When the concentration of methane is close to the stoichiometric concentration or the strength of venting material is higher, the dynamic response of the glass specimen is more violent and even destroyed. At the same time, the finite element software LS-DYNA was used for numerical analysis of the single-layer glass test model. The failure mode and crack distribution obtained were basically consistent with the test results, which verified the reliability of the numerical simulation method.

甲烷-空气混合物泄放爆炸载荷作用下建筑玻璃动态响应的实验研究

摘要 为研究不同建筑玻璃在瓦斯爆炸作用下的动态响应特性和抗变形能力，选取钢化玻璃、夹层玻璃、中空玻璃和浮法玻璃四种建筑玻璃作为试验样品。爆炸试验是在四边固定支撑的条件下，通过改变玻璃试样的厚度、气体浓度和泄爆材料等因素进行的。结果表明，不同类型的建筑玻璃具有不同的抗爆能力，因此在气体爆炸作用下的失效模式和裂纹分布也不同。随着结构层厚度的增加，不同建筑玻璃的防爆能力有所提高。当甲烷浓度接近化学计量浓度或排气材料强度较高时，玻璃试样的动态响应更加剧烈，甚至被破坏。同时利用有限元软件LS-DYNA对单层玻璃试验模型进行数值分析。得到的失效模式和裂纹分布与试验结果基本一致，验证了数值模拟方法的可靠性。
