Abstract
An efficient method is developed for the analysis of scissor-like
foldable structures. The stiffness matrix of a unit of such
structure known as "duplet" is derived and incorporated in
an standard stiffness method. A computer program is
developed and many examples are studied. The results are
compared to the analysis using uniplet elements.
Substantial improvement is obtained through the
introduction of duplets in place of the use of uniplets.
Foldable structures with cable elements are also considered.
