| Limit-point buckling analyses using solid, shell and solid–shell elements Marc Killpack and Farid Abed-Meraim*
The Journal of Mechanical Science and Technology, vol. 25, no. 5, pp.1105-1117, 2011
Abstract : In this paper, the recently-developed solid-shell element SHB8PS is used for the analysis of a representative set of popular limit-point
buckling benchmark problems. For this purpose, the element has been implemented in Abaqus/Standard finite element software and the
modified Riks method was employed as an efficient path-following strategy. For the benchmark problems tested, the new element shows
better performance compared to solid elements and often performs as well as state-of-the-art shell elements. In contrast to shell elements,
it allows for the accurate prescription of boundary conditions as applied to the actual edges of the structure.
