Post-Yielding Behavior of Torsionally Loaded Composite Tubes

Source

Using three post-yielding theories, the results of a laminate test program for in-plane shear are analyzed. In a recently completed test program at the National Aeronautics and Space Administration/Langley Research Center, 36 filament wound tubes were tested in torsion. Shear stress-strain data to the failure points were obtained for a variety of laminates. These data are compared to micromechanics, macromechanics, and quasi-linear analytical laminate predictions. Comprehensive computer codes were used to generate the analytical data. Along with the description of the correlation obtained by each method, the procedure required to implement the method is described in detail in order to identify the relative merits for each procedure.
