脆性材料抗拉强度测试方法的研究

THE METHOD OF TESTING FRAGILE MATERIAL S STRENGTH OF EXTENSION

本文用弹性力学理论对沿直径受压的脆性材料圆盘进行应力分析,得出应力计算理论公式。从而对脆性材料抗拉强度的测定提出了一种新的方法,即通过对圆盘沿直径对心受压试验可测出其抗拉强度。

This article uses mechanics of elasticity theory to analyse the stress of fragile material disk pressed in diametric. From it we can obtain the formala of stress calculating theory. Therefore we point out a new method of testing fragile material's strength of extension. That is to say we can measure the disk's strength of extension by pressing in its diametric.
