A sphere is subjected to a uniform flow of viscous fluid. The velocity of the fluid is considered at infinity. 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).
Консоль загружена поперечной и осевой силой на правом конце и полностью защемлена на левом конце. 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.
В длинной тонкой балке, несущей сосредоточенную массу, она нагружена зависящей от времени силой. It is simply supported. The problem is described using the following parameters. Determine the deflections in the given test times.
Определите максимальный прогиб четырех колонн, закрепленных снизу и соединенных жестким блоком сверху. 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.
