This document provides details of ten benchmark tests for 3-D Beam and Shell Finite Element (FE) assemblies exhibiting getometric non-linear behaviour. Each benchmark test is presented in full, a summary description being given in Ref. 1. The work was commissioned by NAFEMS and undertaken by NNC Ltd under the direction of the Non-linear Working Group (now the CSM Working Group ).
The object of the report is to provide full details of a set of benchmarks problems illustrating the major attributes of geometric non-linear behaviour which a finite element code may be required to deal with when solving ‘real life’ industrial problems. The structures are idealised using 3D beam and shell formulations. Such structures are said to exhibit geometric non-linearity if their response to the loading of the actual deformation or strain. The benchmarks presented here are however restricted to finite displacement, finite rotation and small strain behaviour. Large strain problems are specifically excluded.
The ten benchmarks will:
A summary of the attributes of geometric non-linear behaviour covered by this set of problems is given. The concept of ‘target’, ‘reference’ and ‘published’ solutions is then introduced. Finally, a full description of each benchmark problem and solutions is presented.
