Abstract
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.
