Correspondence on Finite Element Analysis of Geometric Non-Linearity in Plane Frameworks by Dr A.T. Salami and Dr C.T. Morley

Professor F.W. Williams (F) (University of Wales, Cardiff) The authors’ advocacy of the use of the curve length method in finite element analysis is most interesting and they have kindly called attention to the writer’s previous use of this method to obtain analytical solutions4. The writer’s solutions included experimental comparisons for a spaceframe dome as well as two toggles. The object of this correspondence is to comment briefly, to try to improve the authors’ already excellent use of one of the writer’s toggles, as the basis of all their comparisons of results.
