Description

Many of the shell structures with high structural interest have rotational symmetry. This is the case for water tanks, sludge digesters, cooling towers for power plants, nuclear power plants with cylindrical walls and domes, and a large number of non-civil engineering shell structures, such as missiles, pressure vessels, aircraft, etc..

The main advantage in the study of axisymmetric shells is the drastic reduction in the mesh size which increases the calculation efficiency.

AXI-SHELLS uses truncated cones finite element for the structure discretization, following a similar philosophy to the analysis of curved shells with flat elements.
