In elements used as flexible linking devices and structures, the main chara
cteristic is a fairly large deformation without exceeding the elastic limit
of the material. This property is of both analytical and technological int
erests. Previous studies of large deformation have been generally concerned
with a single member (e.g. a cantilever beam, a simply supported beam, etc
.). However, there are very few large deformation studies of assembled memb
ers such as frames. This paper deals with a square frame with rigid joints,
loaded diagonally in either tension or compression by a pair of opposite f
orces. Analytical solutions for large deformation are obtained in terms of
elliptic integrals, and are compared with the experimental data. The agreem
ent is found to be fairly close.
