摘要：
Paper is addressed to reliability and efficiency of functional a posteriori error estimates for Cosserat elasticity in the process of adaptive mesh refinements. A new variant of such error estimate is proposed. Numerical investigations continue previous work of authors. It is shown that functional approach can be not only efficiently implemented for refinements (with MATLAB), but it provides upper bounds for the energy norm of errors without significant overestimations.
