Error Constructing to Move the Discrete Models of Elastic Composites Using Upper and Lower Bound Functions

Numerical procedure to construct the relative errors for maximum movement of finite element models of elastic composites, experiencing the plane stress has been suggested. The standarts containing dimention factors for the known spaces (energetic, Sobolev, L₁ and L₂) have been proposed.

Key words: relative error, functions of the upper and lower bounds, error function, composites, plane elasticity problem, finite elements method, modified standarts, dimention factors.
