Today the finite-element method is the most widely used tool in the prediction of both linear and nonlinear structural behaviour. An inherent danger of such widespread use, however, is an overconfidence in the accuracy and correctness of the results obtained. It is necessary to produce simple benchmark tests which may be performed to justify the user's faith in such finite-element packages. The results of these benchmarks should compare favourably with experimental results, exact theoretical models or with recognised finite-element standards.
