在两个同心圆柱体的两个半径半径之间的各向同性预应力拉伸膜,该预应力位于一个不与竖轴平行的平面上。 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.
