Curved Thick Shell and Membrane Elements with Particular Reference to Axisymmetric Problems

Abstract

General curved isoparametric elements in two and three dimensions are degenerated to deal with axi-symmetric and arbitrary shells. By introducing only some of the usual Navier assumptions, these new shell elements can include shear as well as bending deformations. It is shown that, even for very thick shells, excellent accuracy is retained. By further degeneration membrane situations are dealt with.
