摘要
在玻璃上预制可控表面裂纹，测得裂纹沿长度方向的扩展数据，利用裂纹扩展阻力曲线，对表面裂纹的扩展作数值模拟，得到裂纹深度和深长比数据。为了解表面裂纹的扩展过程提供依据。
In this paper we have prepared controllble surface cracks on glasss pecimens and measured the extension data along crack length. By themethod of crack extension resistance curve a numerical simulationon the surface crack extension is made and the data on the crack depth andthe ration of depth to length are obtained respectively, providing the basis for deeply understanding the propagation proccess of surface cracks.
