The stress intensity factors along the crack front are calculated for straight-fronted edge cracks in bars with circular cross-section subjected to tension or bending loading. The results are deduced by means of a three-dimensional finite element analysis and the stress field singular behaviour in t

## Abtmct -An internal crack problem in a semi-intktite plane under uniform tension is taken as a sample problem to estimate accuracy for the calculated stress intensity factors (SIF). The problem is reduced to a solution of the singular integral equation. After the approximate solution of the sin
When these data are applied to the formula derived by M. A. Schroedl and C. W. Smith, the stress intensity factor K, can be calculated. Comparing this computed K, with that given by theoretical formula, we have found the error to be within t 5.20%. It is believed that the result of this test has met
