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.
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.
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.
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.
