Ein Mauerwerk ist in der Mitte seines oberen Querschnitts einer verteilten Last ausgesetzt. The Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic model, with surface stiffness property Without Tension in the nonlinear calculation.
Eine zylindrische Membran wird anhand isotroper Vorspannung gedehnt. Find the final minimal shape of the membrane - catenoid. Determine the maximum radial deflection of the membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Bestimmen Sie die maximale Durchbiegung von vier unten befestigten Stützen, die oben durch einen starren Block verbunden sind. 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.
Eine kugelförmige Ballonmembran wird mit Gas mit Atmosphärendruck und definiertem Volumen gefüllt (diese Werte werden nur für die FE-Modelldefinition verwendet). Determine the overpressure inside the balloon due to the given isotropic membrane prestress. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Vier Stützen sind unten fixiert und oben durch einen starren Block verbunden. 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.
Ein gedämpftes Einmassensystem wird einer konstanten Lastkraft ausgesetzt. 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 cable is loaded by means of a uniform load. Das hat eine deformierte Form in Gestalt von einem Kreissegment zur Folge. Determine the equilibrium force of the cable to obtain the given sag of the cable. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Ein Kragarm ist am linken Ende vollständig befestigt und am rechten Ende durch eine Querkraft und eine Normalkraft belastet. The tensile strength is zero and the behavior in the compression remains elastic.
Eine Membran wird anhand isotroper Vorspannung zwischen zwei Radien von zwei konzentrischen Zylindern gedehnt, die nicht in einer Ebene parallel zur vertikalen Achse liegen. Find the final minimum shape of the membrane - the helicoid - and determine the surface area of the resulting membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Dieses Verifikationsbeispiel basiert auf dem Verifikationsbeispiel 0122. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
