Abstract
A new a posteriori error estimate for Cosserat elasticity is proposed. Paper continues implementations of functional approach to error estimation for planar problems of classical and Cosserat elasticity. The proposed majorant is reliable regardless of some additional assumptions (for instance, the Galerkin orthogonality). This property is preserved independently of methods used for solving a problem, and the estimate is valid for accuracy control of any conforming approximate solution.
