One-Dimensional Orthotropic Plasticity - 4 Columns
Determination of the maximum deflection of the four columns fixed at the bottom and connected by the rigid block at the top. Block is loaded by the pressure and modeled by an elastic material with high modulus of elasticity. Outer columns are modeled as orthotropic elastic material and inner columns as orthotropic elastic-plastic material with the same elastic parameters as outer columns and with plasticity properties defined according to the Tsai-Wu plasticity theory.
