ABSTRACT
ABSTRACT: In order to keep the character of high-speed and high-accuracy of the numerical system applicable to fracture mechanics, a way to establish analytical formula for the influence coefficient of square-root crack edge element of three-dimensional displacement discontinuity method with boundary division into triangular leaf elements is found. This is realized by the aid of symbolic computation of Mathematica. It proves valid by comparing the computation with the existing semi-numerical integration
