ABSTRACT
The author published some very limited design tables in Ref. 2.1. These were produced by his colleague Dr I. Khwaja writing computer programs to solve the analytical method suggested by Gibson, Ref. 2.2 as his 'degenerate theory'. This theory uses cylindrical shell theory and flattens out these shells (degenerates them) and tilts them to make systems of folded plates. For the cylindrical shell theory, Dr Khwaja used the very accurate, comprehensive and complex DJK elastic analysis, Ref. 2.3.
