Title: Analysis Of Laminated Tubular Structure Under Torsion
Author: Chomtid, Thana
Abstract: Laminated composite shells in particular are prominent in bearing various types of loads and are hence used in many engineering structures. The analysis of laminated composites is quite complicated since the material behavior is anisotropic, which gets further intensified in the analysis of complex structures like tubular structures. Finite element method is a useful method for evaluating and conducting the behavior of thin laminated tubular structure subjected to torsion. In this study, the behavior of shear stress versus angle along the laminated tubular structure cross section was conducted in varies radius ratio which are 1, 0.8, 0.6, 0.4, and 0.2 on different fiber orientation which are symmetry and antisymetry. The results reveal an unsteady behavior pattern on the high curvature section that effected when the radius ratio is reducing to a small number. However, in the high radius ratio the tubular structure shear stress is identical to laminate theory
