Analysis of Titanium-matrix Orthotropic Cylindrical Shell Subjected to Thermomechanical Loading

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.
