| 摘 要： | 玻璃面板的强度设计中 ,带孔玻璃板孔边的破坏应力至今尚没有方便的公式来计算 ,目前设计中孔边应力一般不予计算 ,然而孔边应力恰是强度设计中应力控制的一个关键点。在试验的基础上 ,通过曲线拟合和插值的方法得到了带孔玻璃板的孔边破坏应力 ,为点支承玻璃板的设计提供了参考。

| Abstract: | In the strength design for the point-supported glass plane,the calculation for the stress near the hole is often ignored due to the complexity of the stress distribution around the hole.The stress distribution has been deduced under the condition that the loads and the geometrical configuration of the system are all axially symmetric.On the basis of the experiments,the breaking stress near the hole is obtained by interpolation. |
