| Abstract: | 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. |
