“…Another way is reasonable simplification of the elasticity problem statement, for example by using the membrane theory or other shell theories [30,32,33], that leaves the question of results validity. This is the approach we have applied in our study.…”

This chapter is devoted to modeling the properties of composite materials and structures. Mathematical relations describing the nonlinear elastic three-point bending of isotropic and reinforced beams with account of different strength and stiffness behavior in tension and compression are obtained. An algorithm for numerical solution of corresponding boundary-value problems is proposed and implemented. Results of numerical modeling were compared to acquired data for polymer matrix and structural carbon fiber reinforced plastics. A computational technology for analysis and optimization of composite pressure vessels was developed and presented.

In its most general form, a pressure vessel consists of two main parts; the cylindrical part and the dome part. This paper presents the analysis that has been conducted in order to obtain the optimum shape of the filament wound dome part. A composite pressure vessel with optimized dome ends avoids critical stresses that are incorporate with the structure when the structure is internally pressurized. The analysis deals with domes with/without polar opening. Analytical models are developed based on mechanics of materials, geodesic analysis and are solved using numerical techniques. The models can predict both the optimum shape and optimum thickness of the dome part that can safely withstand the applied loads with minimum weight. The results have been verified using published work with good agreement. Finally, the models have used to investigate the effect of changing material type, material properties on the optimum shape of the dome part.

In this article, the effects of several slippage coefficient distributions on the geometry, fiber trajectories, and the structural efficiency of non-geodesic domes are evaluated for composite pressure vessels. Several functions, which ensure C 1 continuity of the winding trajectories, are respectively used to describe the slippage coefficient distributions along the fiber paths. With the aid of the fiber slippage law and the optimality condition of equal shell strains, the differential equations that govern the non-geodesics-based dome shapes and related fiber trajectories are formulated. The meridian profiles and winding angle developments of the carbon-epoxy domes are obtained based on the given slippage coefficient distributions; their structural performances are then determined and compared with each other. The results conclude that the nongeodesic dome designed using the maximum constant slippage coefficient exhibits better performance than those using other slippage coefficient distributions; this is mainly triggered by maximum utilization of the longitudinal strength of the laminate. It is also revealed that the structural efficiency of domed pressure vessels can be improved using non-geodesics that provide higher degrees of freedom in the design of filament wound structures.
