摘要：
The estimation of a stress-strain state of a steel vertical tank with an initial semi-elliptical crack under the action of hydrostatic pressure is performed. The distribution of stress intensity factors along the crack front is obtained. A comparison of the results obtained using of semi-analytic finite element method and of finite elements, being used in different software packages, is made.
