Una membrana se estira por medio de un pretensado isótropo entre dos radios de dos cilindros concéntricos que no se encuentran en un plano paralelo al eje vertical. 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.
Una membrana cilíndrica se estira por medio de un pretensado isótropo. Find the final minimal shape of the membrane - catenoid. Determine the maximum radial deflection of the membrane.
