| Abstract: | The deformation localization process for coal and rock in mining engineeing is studied through white light digital speckle correlation method in this paper. The starting point and evolution of localization band, and also the width of localization band is obtained. The results are useful for studying the non homogeneous deformation evolution process and the mesoscope constitutive relations in rock materials. |
