Abstract

The finite element analysis of rods using an "updated-Lagrangian" formulation is extended to problems with unilateral constraints. The rods are described according to Timoshenko's bending theory, undergoing large displacements and rotations, with restriction to small strains. The critical loads are given as a result of an incremental computation process, which simultaneously approximates the geometrical nonlinearities as well as the nonlinearities arising from the unilateral constraints. A computer program was written in FORTRAN IV, and the results obtained present good agreement compared with analytical solutions or other numerical solutions in literature.
