Full Article:

This paper describes the use of Topology Optimization Method (TOM) as a strong technique to the design of fully compliant mechanisms considering nonlinear elasticity. To the best knowledge of the authors, previous works on the design of those mechanisms didn’t address the problem related to the objective, constraints function, numerical optimization algorithm considering a polyconvex constitutive model for well-posedness of the governing equations. The optimization problem is set to find the configuration that has the maximum displacements when subject to a prescribed displacement or force, volume constraint, and equilibrium. The material model used was the SIMP, and tests were performed using OC, MMA, and SLP algorithms. The results are presented to compare the proposed methodology with the traditional TOM methodology.
