Abstract Solutions of dynamic stress intensity factor of several models were obtained accurately, using ANSYS commercial FEM software, adopting non-singular elements and the Newmark Integral Method, through least square fitting. The method can be used widely for general purpose, which was beneficial and necessary for using linear elastic fracture dynamic to solve practical engineering problems.
