中文摘要：
研究了有机玻璃边缘连接元件在不同温度下的拉伸和弯曲疲劳特性。实验结果表明：温度对有机玻璃边缘连接元件静强度、刚度影响很大;温度升高,有机玻璃边缘连接元件结构拉伸强度、刚度大幅度降低,同寿命下拉-拉疲劳强度也明显降低;而弯曲强度和同寿命下弯曲疲劳强度在室温时最低,低温时最高。
英文摘要：
Tension and bending fatigue tests were carried out to investigate the fatigue behavior of polymethyl methacrylate for edge attachment element at different temperatures.Test results showed that the fatigue performances of the whole edge attachment assemble were extraordinary sensitive to experimental temperature.With increasing of temperature,the captive tension strength and tension fatigue strength decreased evidently.The captive bending strength and bending fatigue strength at uniform lifetime were maximal at lower temperature,and were minimum at room temperature.
