Study on the statistical model of rock damage based on twin shear unified failure criterion

Abstract
By using the form of new rock micro-unit strength based on Twin Shear unified failure criterion,which satisfies weibull random distribution,a statistical damage constitutive model was developed.The parameters have been gotten by using the method for calculating the extremity of function according to the extremity characteristics of rock deformation curve.Comparison with the result of triaxial compression tests shows that this model can reflect...
