Abstract

In this investigation, the magnitude and position of the maximum stresses, as well as the stress distributions at critical sections of internally loaded conduits, were determined by experimental photoelasticity. The conduits tested had circular internal boundaries and square, octagonal and sixteen-sided polygon external boundaries. The photoelastic material used to make the models was Catalin 61-893.

Curves of stress distribution have been plotted for the various shapes and sections, making rapid and economical design of the shapes possible.

A technique for applying known internal pressures to conduit photoelastic models was developed in order to carry out the investigation. This involved a fixture embodying a rubber pressure disk and a helical spring.
