Une plaque orthotrope carrée en couches est complètement encastrée en son point central et soumise à la pression. Compare the deflections of the plate corners to check the correctness of the transformation.
Un bloc tridimensionnel en matériau élastique-plastique est fixé aux deux extrémités. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
Déterminez la flèche maximale d'un bloc 3D encastré à ses deux extrémités. The block is divided in the middle: the upper half is made of an elastic material and the lower part is made of timber - an elasto-plastic othotropic material with the yield surface described according to the Tsai-Wu plasticity theory. The block's middle plane is subjected to vertical pressure.
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.
Une poutre en bois renforcée par deux plaques en acier aux extrémités est chargée en pression. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described according to the Tsai-Wu plasticity theory.
Un bloc tridimensionnel en matériau élastique-plastique avec durcissement est fixé aux deux extrémités. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai‑Wu plasticity theory.
Une plaque large avec un trou est chargée dans une direction par une contrainte de traction. The plate width is large with respect to the hole radius, and it is very thin, considering the state of the plane stress.
Une poutre en bois renforcée par deux plaques en acier aux extrémités est chargée en pression. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described according to the Tsai-Wu plasticity theory.
Quatre poteaux sont encastrés en bas et reliés 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 by linear elastic material and the inner columns by a stress-strain diagram with decaying dependence. Assuming only the small deformation theory and neglecting the structure's self-weight, determine its maximum deflection.
Déterminez la flèche maximale du porte-à-faux composé de deux couches de verre et d'une couche de feuille entre les deux. The plate is fully fixed at one end and subjected to uniform pressure.
