Abstract : The purpose of this program is to determine the presence and magnitude of residual stresses in thick wall fiberglas structures, and their effect on material properties; such that, the information will be applicable to full size deep submergence structures, and detrimental effects may be minimized or eliminated. Residual stresses are reported for eight dispersed construction cylinders and eight all-hoop tape wound rings. Interlaminar shear strength and related trends for the cylinders are included. Four methods for analysis of residual stress are compared, and general orthotropic thermal effects are analyzed. (Author)
