The accuracy of the finite element calculation of the J^^-integral, which represents the dynamic energy release rate for propagating cracks, is studied. The main error is found to be caused by the calculation of the singular area integral. In order to reduce the error, a new method for evaluating the singular area integral. In order to reduce the error, a new method for evaluating the singular area integral is developed. In this method, the integrand in the singular area integral is developed. In this method, the integrand in the singular area integral is approximated by a certain function which is transformable into a line integral. The line integral is then evaluated analytically. The usefulness of the present method is demonstrated by an elastodynamic example.
