rock toughness

基本解释

An experiment on dynamic rock fracture toughness test using edge-notched disc specimen is presented.
提出用边切槽圆盘试样测量岩石动态断裂韧度的实验方法。
Based on these and different assumptions, the rock fracture toughness has been determined with rock fracture toughness testing system, which is self-developed and has the internal pressure.
在此基础上，应用自主研制的内压法岩样断裂韧性测试系统对不同假设条件下的岩石断裂韧性进行测定。
Therefore, by means of fractal geometry study on fractured surfaces of rock, it is possible that the rock fracture toughness and loading rates at which the rock fractures can be obtained directly.
这说明通过辉长岩断裂面的分维数测量与分析，有可能直接获得断裂韧度值以及断裂时经受的加载率等数据。
