Plasticité orthotrope unidimensionnelle - 4 colonnes

Déterminez la flèche maximale de quatre poteaux encastrés en bas et connectés par un bloc rigide en haut. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled as orthotropic elastic material, and the inner columns as orthotropic elastic-plastic material with the same elastic parameters as the outer columns and plasticity properties defined according to the Tsai-Wu plasticity theory.
