Abstract : A titanium-matrix orthotropic cylindrical shell with the principal direction of orthotropy following a parallel constant angle helix, has been studied when it is subjected to uniform loading conditions of internal pressure, axial load and pure twisting moment. Nondimensional parameters pertaining to loading and deformations have been calculated and results plotted. The results obtained can be usefully applied in robotic actuators where lightweight considerations with high strength are of prime importance. The study is further extended to investigate the effect of temperature on the deformations. Through parametric studies, deformation patterns are calculated and plotted that are unique to orthotropy. In most of the cases, it is observed that deformation patterns are same, but deformation is increasing with temperatures. |
