The
8-nodes axi-symmetric membrane
element is available in XFINAS
. The plasticity is handled
by applying the Von Mises yield
condition and Prandl-Reuss flow
rule at discrete points through
the membrane wall. The example
of the nonlinear dynamic analysis
in Fig . 17 is in good agreement
with reference.
