Abstract

Conventional error analyses norms in the finite element method are based on the percentage error or its equivalent in some computed value as compared to the theoretically predicted value. In this paper, the author develops a simple basis for classifying 'errors of the second kind' which arise due to the 'spurious constraints' imposed by certain formulations. He shows how simple error models based on this error estimate may be related to the geometrical/structural parameters that cause a severe deterioration of results when these parameters take large values in a limiting penalty function sense.
