Wi. Thacker et al., STABILITY AND POSTBUCKLING OF A PLATFORM WITH FLEXIBLE LEGS RESTING ON A SLIPPERY SURFACE, Mechanics of structures and machines, 26(3), 1998, pp. 277-286
A rigid platform is supported by thin elastic legs. The legs are able
to slide on the ground as they deform. The governing equations for lar
ge deformations are formulated and solved numerically by homotopy and
quasi-Newton methods. Nonlinear phenomena such as nonuniqueness are fo
und. A global critical load for nonlinear stability is presented.
