Abstract
We test the performance of standard finite element approximations
of varying degree in three simple benchmark
shell problems in cylindrical shell geometry. The exact
solutions to these problems are computed both numerically
and symbolically. We demonstrate by these problems
that seemingly similar shell problems can be quite
different in their mathematical character, and that this
hidden diversity is strongly reflected in the performance
of the standard low-order finite element methods. We also
demonstrate that raising the degree of the elements as
a rule highly improves the accuracy and makes the finite
element scheme more robust.
