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:
- allow verification and searching checks of the ability of finite
element computer codes to produce acceptable solutions to problems
involving geometric non-linearity in structures idealised by
assemblies of 3-D shell or beam elements.
- exercise a user’s ability to model physical behaviour and
interpret results from non-linear finite element analysis.
- Allow education/training of inexperienced persons with respect to
the use of finite element packages in solving non-linear problems.
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.
