Abstract:

A methodology is presented for constructing an exact stress solution for a multiorthotropic-layered cylinder for which all layers have equivalent axial strain. Combined loadings of internal pressure, external pressure, and axial force are included in the solutions formulation. The multilayered solution is developed by applying the proper boundary conditions to a three- dimensional elasticity solution for a monolayered orthotropic cylinder. Theoretical results for multilayered cylinders with selected material layups and loading conditions are compared with finite element results to verify the accuracy of the solutions formulation. The software implementation of this solution provides the design engineer with a powerful tool for efficiently using composite materials in cylindrical pressure vessels.
