Ultimate state of a plate with several holes

A theoretical method is proposed for determining the ultimate state of a plate with several holes based on strength criteria of fracture mechanics and continuum mechanics. The ultimate state of a plate of finite width with two holes was found by the given method. As a result of realizing the indicated method, methods were developed for determining the stress state of a strip with two holes and the stress intensity factors in a strip with radial cracks extending to the edges of two holes. The maximum difference between the experimental and theoretical data (by the proposed method) does not exceed 12%.Translated from Problemy Prochnosti, No. 3, pp. 44–52, March, 1994.
