The paper presents a short overview of selected problems related to the numerical analysis of localized deformations. After defining the localization phenomenon and the class of gradient models, two simulation examples are shown. They are applications of the plasticity theory with a Laplacian of the hardening parameter and of the damage theory with an additional averaging equation for an equivalent strain measure.

Artykuł przedstawia krótki przegląd wybranych problemów analizy numerycznej deformacji zlokalizowanych. Po zdefiniowaniu zjawiska lokalizacji i klasy modeli gradientowych zwięźle opisano dwa przykładowe zastosowania teorii płynięcia plastycznego zawierającej laplasjan parametru wzmocnienia i teorii uszkodzenia z dodatkowym równaniem uśredniającym miarę odkształcenia w otoczeniu punktu.
