In this paper, a numerical solution has been developed for hollow circular cylinders made up of orthotropic material which is subjected to twist using micro polar theory. The effect of twisting moment and material internal length on hollow thick-walled circular cylinder made up of micro polar orthotropic material is investigated. Finite difference method has been used to exhibit the influence o...

This problem was suggested by Bradley Klee. For the related case of one cylinder rolling inside another, see [1]. When one cylinder is directly above the other, we define the line of contact of the lower cylinder, 1, with the horizontal plane to be the z-axis, at x = y = 0. Then, the condition of rolling without slipping for the lower cylinder is that when it has rolled (positive) distance x1, ...

We consider the co-axial cylindrical structure as a composite submerged solid cylinder above special bottom undulation, i.e., circular plate at impermeable horizontal bottom. diffraction problem of proposed in water finite depth. This can be expressed wave energy converter. The variables separation and eigenfunction expansion methods are utilized to determine analytical solutions for their iden...
