Abstract:
The finite element method was used to analyse a number of domed structures. Two new sandwich plate bending elements (rectangular and triangular) were devised. They were used to produce results for comparison with other solution methods. The agreement was excellent. They were also used to produce results for comparison with experimental work on sandwich plates. The agreement varied. To the triangular element was added a plane stress component, together with suitable apparatus for making transformations at plate boundaries. This element was used to solve three tetrahedral domes, a square pyramid, a hexagonal dome, and a 16-faced dome. All these were investigated experimentally. The agreements varied between very good and moderate. A comparison was also made with the only other published results on a sandwich folded plate structure, due to Benjamin. In conclusion some improvements were suggested.
