ON THE MUTUAL INFLUENCE OF CLOSELY LOCATED CIRCULAR HOLES WITH RIGID CONTOURS IN A SPHERICAL SHELL

摘要

We consider a problem of the stressed state of a shallow isotropic spherical shell containing two circular holes with rigid undeformable contours. The cases of rather close location of contours with both equal and unequal radii in the shell under an internal pressure are numerically investigated. It is established that stresses in the bridge between the contours increase substantially as the distance between them decreases.
