The finite element method (FEM) is useful for the stress analysis and used
widely in general.
However, it is still not necessarily easy to obtain the highly
accurate values of stress intensity factors by FEM.
Recently, a method for calculating the highly accurate values of stress
intensity factors in two-dimensional crack problems has been proposed by H.
Nisitani, based on the usefulness of the stress values at a crack tip calculated
Although this value at a crack tip by FEM is finite, it is very
effective as a measure of the singular stress field of the crack tip.
In this study, an extension of this method to the round bar with
circumferential crack was made.
The extended method was applied to the
tensile problems of a round bar with a si...
