Um sistema de massa singular com amortecimento está sujeito a uma força de carga constante. Determine the spring force, damping force, and inertial force at the given test time. In this verification example, the Kelvin--Voigt dashpot (namely, a spring and a damper element in serial connection) is decomposed into its purely viscous and purely elastic parts, in order to better evaluate the reaction forces.
A steel cantilever with a rectangular cross‑section is fully fixed on one side and free on the other. O objetivo deste exemplo de verificação é determinar as vibrações naturais da estrutura.
A column is composed of a concrete section (rectangle 100/200) and a steel section (profile I 200). Está sujeito a uma força de compressão. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
A truss structure consists of three rods (one steel and two copper) joined by a rigid member. The structure is loaded by a concentrated force and a temperature difference. Determine a flecha total da estrutura, sem considerar o peso próprio.
A timber beam reinforced by two steel plates at the ends is loaded by pressure. The wood fibers are parallel to the upper loaded side of the beam. A superfície plástica é descrita de acordo com a teoria da plasticidade de Tsai-Wu.
