Summary

The aim of the study, described in this paper, was to computationally analyse the experimental results of buckling tests, carried out on carefully machined steel cones subjected to combined axial and lateral pressure. Ten steel cones were tested experimentally and all were analysed in this paper; two with just under external lateral pressure, two with just under external axial pressure and six with combined axial and lateral pressure. The computer program ANSYS was used to simulate the practical experiments, for the first time; conducting Eigen-buckling and non-linear buckling analyses on each of the ten conical shells. The experimental results were obtained from previous testing. ANSYS produced results similar to the experiments showing that the majority of the cones failed as a result of shell instability. The nonlinear plastic buckling results calculated using ANSYS were also accurate for the majority of cones. The nonlinearity analyses included material and geometrical nonlinearity. Two other design codes were also used to compare with the experimental values; namely ABAQUS and BOSOR5; but these programs could not replicate the high levels of accuracy to the same degree as that demonstrated by ANSYS. The result of this paper demonstrate that ANSYS could be a realistic alternative to physical testing, and also proved to be modestly more accurate than ABAQUS and BOSOR5.
