The Study of Relationship between Rock Crack CT Image Tensor Representation Sign and its Destruction Features

Abstract:

By using the mine coal sample (DT - 3) and its CT image sequences, the application of stereology knowledge from the two dimensional perspective gets the DT - 3 CT images were a series of calculation for characterization of crack of second order tensor, and that the second order tensor of the characteristic value can be a very good explanation coal samples in a single shaft confining pressure under the action of the whole process of mechanical failure mechanism.
