Experimental and theoretical results of the internal hydro static pressure of multilateral pipes

Dr. EmadTomaKarash

The experimental research of glass-epoxy circular laminated platewith defects stress has been made. Three variants of the multi-layer anisotropic shell computational model according to the discreet-structural lamina theory are considered in this paper. This model consists of several stiff anisotropic layers. It is considered, that transversal shear and thickness reduction stresses are equal on the contact boundary. At the same time, the elastic sliding between adjacent layers contact boundaries are permitted. Theoretic results are compared with experimental oneÂ’s and found satisfy matched.
