On Computational Evaluation of Stress Concentration Using Micropolar Elasticity

We discuss the implementation the finite element approach to the linear micropolar elasticity in order to perform the analysis of the stress concentration near holes and notches. Within the micropolar elasticity we analyze the behaviour of such microstructured solids as foams and bones. With developed new finite element few problems are analyzed where the influence of the microstructure may be important. The provided comparison of solutions obtained within the micropolar and classical elasticity show the influence of micropolar properties on stress concentration near notches and contact areas.
