Finite Element Benchmarks for 2D Beams & Axi-symmetric Shells Involving Nonlinear Geometric Behaviour

This document is a summary of the benchmarks discussed in PO4. The purpose of these reports are to provide a set of benchmark tests against which the results of different finite element programs can be compared. The report is concerned with solutions to problems involving thin two-dimensional beams and axisymmetric shells undergoing large displacements and rotations. Problems involving deep beams, large strains or non-conservative loading are specifically excluded. 

Furthermore the beams and axisymmetric shells are assumed to have elastic material properties and a prismatic cross section.The emphasis on the results in this report lies in the area of displaced shapes and thus most of the target results quoted relate to displacements rather than internal stresses. However, stress resultant plots obtained from the Finite Element solutions have been included for all the beam tests along with values for stress resultants obtained by simple statics for those tests which are statically determinate.
