Benchmark Tests For Various Finite Element Assemblies

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 of 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.
