Numerical evaluation of stress Intensity factors in jointed rock medium by the M-integral method

  Determination of stress intensity factors is a critical task in fracture mechanics, numerical methods such as the finite element and boundary element methods which have successful applications in various fields of engineering problems, encounter mesh-related difficulties in dealing with fracture mechanics problems, to overcome these difficulties, a number of meshless methods have been developed in recent...
