Results

View results of the composite tube analysis using pre-failure nonlinearity.

The plot below shows the displacement of the nodes located on the outer radius of the top surface of the tube for cases when pre-failure is turned off and when it is turned on. The displacement of the model run without pre-failure is linear up to a displacement of 0.0016 m, at which point matrix constituent failure occurs throughout the model. With pre-failure on, the displacement is linear up to a displacement of 0.00071 m, then diverges from the pre-failure off results as a consequence of the three discrete reductions in shear stiffness that occur prior to matrix failure. Note the significant difference in displacements at failure between the two curves. With pre-fail off the displacement is 0.0016 m and with pre-fail on the displacement is 0.0052 m.
