"Models of epoxy resin were used in a stress freezing technique to determine areas of possible failure in lined circular openings. These models were loaded in a centrifuge for a fixed period of time, after which they were analyzed photoelastically. The material characteristic changes, with time, were recorded on graphs and used in the analysis.
Two types of tests were conducted; one, where the lining thickness was changed and, the other, where materials of the liner and plate material were changed.
The resulting analyses furnished proof that the greater the rigidity of the lining, the higher the stress developed in the lining, and also, as the lining thickness increased, holding liner inside diameter constant, the stress decreased in the lining and plate material"--Abstract, page i.
