| Abstract: | According to the study on breaking mechanism experiment of rock mechanics （ taking the logarithmic model equation of Mohr sandstone and mudstone of rock, in combination with indoor as samples）, we have established envelop and calibrated parameters of it. Then, the application area of Mohr envelop, variation trend and breaking mechanism of rock are cognized, which can simplify the study of breaking intensity of these rocks and extend into other experiments of rock mechanics. |
