STRESS ANALYSIS OF A CONICAL ACRYLIC VIEWPORT

Abstract

A balanced format, consisting of both an experimental and an analytical approach was followed to perform a stress analysis of the view port design. Acrylicplastic was chosen as material for view port. All results indicated that view ports with this design exhibit both plugging and bending behavior and have two areas of high stress concentration. The analytical investigation indicated that the surface finish of the flange significantly affects the view port stress distribution. Appendix C describes the experimental measurement of the modulus of elasticity and Poisson's ratio. The modulus of elasticity was found to equal 444,000 psi; Poisson's ratio, 0.4; and the bulk modulus of elasticity,740,000 psi for the acrylic plastic test specimens. (KF- PL)
