Abstract:

A series of pressure vessels was exposed to water, 100 relative humidity and humidity cycling both in their as wound conditions and after they had been prestressed to 80 of their bursting load. The resulting final burst measurements were all subjected to a Student t test to determine the significance of the effects of water. It appears that a reduction of strength at the 0.95 significance level occurs only to specimens that have been preloaded to 80, exposed to relative humidity 100 at room temperature for one week, or immersed in water for one week. One months exposure to humidity cycling does not appear to reduce the strength significantly and there appeared to be no reduction in strength unless the vessel had been previously preloaded. Author
