钠钙玻璃 (SLG) 是一种高度可用的低成本玻璃配方，常用于窗户应用。在过去的十年中，有许多研究检验了这种材料的休格尼奥弹性极限 (HEL)，得出的值范围很广，从 3.1 到 6.0 GPa。 HEL 的确定因许多因素而变得复杂，包括由于低压下雨贡尼奥的凸向下曲率而导致的斜坡载荷。提出并分析高达 20 GPa 的透射波剖面实验结果，以确定 HEL 附近 SLG 的加载和释放特性。结果表明，响应比许多材料典型的弹塑性响应更复杂，这可能解释了最初报道的 HEL 值的广泛范围。
Soda‐lime glass (SLG) is a highly available low cost glass formulation commonly used in window applications. Over the past decade, there have been a number of studies which have examined the Hugoniot elastic limit (HEL) of this material resulting in a wide range of values from 3.1 to 6.0 GPa. The determination of the HEL is complicated by many factors including ramp loading due to the convex downward curvature of the Hugoniot at low pressures. Results of transmitted wave profile experiments up to 20 GPa are presented and analyzed to determine the loading and release characteristics of SLG near the HEL. Results indicate a response that is more complex than the elastic—plastic response typical of many materials, possibly explaining the wide range in initially reported HEL values.
