Abstract:	Variable curvature mirrors of large amplitude are designed by using finite element analysis. The specific case studied reaches at least a 800 {mu}m sag with an optical quality better than {lambda}/5 over a 120 mm clear aperture. We highlight the geometrical nonlinearity and the plasticity effect.
