Results of a theoretical and experimental investigation of stresses in radially deformed perforated flanges are presented. The theoretical analysis considers the plane-stress problem of an annular disk perforated by a ring of equally spaced holes of equal diameter. The experimental portion of the investigation involves strain-gage determinations of stresses in flanges with various numbers of perforations in which the flanges are loaded by a special machine designed for the application of isotropic stress fields to circular bodies. Numerical results are given for a variety of configurations and edge conditions.

An infinite thin plate with an elliptical hole reinforced by a confocal elliptical ring is subjected to loads in the plane. A solution to the generalized plane-stress problem is obtained using the complex variable techniques of Muskhelishvili. The result is presented in a form well suited to evaluation by digital computers. Specialization to a circular hole with a negligibly thin reinforcement is shown to be in agreement with results obtained by other authors.

Plane Stress Problem

A baseline study has been carried out to assess the accuracy of the engineering approach for J-integral determination when applied to various standard specimens. Detailed finite element calculations were used to assess the accuracy of this approach. Although certain discrepancies were found when comparing the approximated functions obtained in this work to those in previous work, the error trends are similar and consistent throughout the analysis. Then, the engineering approach outlined in the baseline study is applied to the 2-D plane stress problem of a C-shaped specimen subjected to tension. Derivation of limit-load, fully plastic solutions and elastic-plastic estimation formulas are given in detail. Detailed comparisons between results from estimation solutions and finite element calculations are presented.
