A sphere is subjected to a uniform flow of viscous fluid. La vitesse du liquide est considérée comme infinie. The goal is to determine the drag force. The parameters of the problem are set so that the Reynolds number is small and the radius of the sphere is also small, thus the theoretical solution can be reached - Stokes flow (G. G. Stokes 1851).
Un porte-à-faux est chargé par une force transversale et un effort normal à l'extrémité droite et est entièrement encastré à l'extrémité gauche. The problem is described by the following set of parameters. The problem is solved by using the geometrically linear analysis, second-order analysis, and large deformation analysis.
Une poutre longue et mince supporte une masse concentrée et est chargée par une force dépendante du temps. It is simply supported. The problem is described using the following parameters. Determine the deflections in the given test times.
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.
