Benchmark Tests For Various Finite Element Assemblies





















This report on proposed benchmarks for static finite element tests supercedes a previous interim report. It is self-contained and includes, where helpful, theory of references to analytics material in appendices. A set of basic system performance tests have been developed which use a simple geometry. These are followed by a set fo membrane assemblies designed to test element behaviour under various mechanical  and thermal loadings and this theme is continued  for plate bending elements. Several three dimensional shell benchmarks are defined and finally folded plate beam is examined. All benchmarks have target figures evaluated to at least 1% accuracy and in all cases the typical performance of a finite element system is quoted.
