This paper deals with the elastic stresses of internally or externally pressurized long thick-walled composite cylinders fixed ends. Cylinders are made unidirectionally aligned transversely isotropic fibers and matrix. Axial radial fiber alignments considered, analytical solutions derived accordingly. Effects direction volume fraction alteration on limit analyzed. It is observed for both intern...

The conventional elastic analysis of thick walled cylinders to final radial & hoop stresses is applicable for the internal pressures up to yield strength of material. The stress is directly proportional to strain up to yield point Beyond elastic point, particularly in thick walled cylinders. The operating pressures are reduced or the material properties are strengthened. There is no such existi...

In the present paper, an exact solution for transient response of an infinitely long functionally graded thick-walled cylinder subjected to dynamic pressures at the boundary surfaces is presented for arbitrary initial conditions. The cylinder is assumed to have a plane-strain condition and the dynamic pressures are assumed to be imposed uniformly and axis...

A heuristic is proposed for a problem that occurs in the design of thick composite cylinders: the selection of the angles of wrap of all the layers forming a cylinder for given material properties and layer thicknesses. The heuristic consists of a local search algorithm that improves on a given initial design by modifying the angle of a single layer in each iteration. Each design is evaluated b...

in the present paper, an exact solution for transient response of an infinitely long functionally graded thick-walled cylinder subjected to dynamic pressures at the boundary surfaces is presented for arbitrary initial conditions. the cylinder is assumed to have a plane-strain condition and the dynamic pressures are assumed to be imposed uniformly and axisymmetrically on the boundary surfaces. m...
