Study on grey feature of surface strain field during deformation and failure of coal rock mass
In order to characterize the deformation and failure law of coal rock, this paper carries out uniaxial compression tests of coal rock specimens, and obtains grey scale images of surface strain field by using digital speckle observation system. Based on the grey scale images of the surface strain fie...
