The paper presents a two-field formulation of the gradient-enhanced damage model and its application. This isotropic model is characterized by two damage parameters with a volumetric-deviatoric decomposition. However, one strain measure governs the development of damage as for the scalar description. The theory is verified by means of one-element benchmarks and also a more sophisticated simulation, namely the splitting of concrete cylinder in the Brazilian test is discussed.

Artykuł przedstawia dwupolowe sformułowanie gradientowego modelu mechaniki uszkodzeń i jego zastosowanie. Ten izotropowy model charakteryzują dwa parametry uszkodzenia z podziałem aksjatorowo-dewiatorowym. Jednakże jedna miara odkształcenia decyduje o rozwoju uszkodzenia jak w opisie skalarnym. Teoria jest zweryfikowana za pomocą testów jednoelementowych, a także bardziej zaawansowanej symulacji rozłupywania betonowego cylindra w tzw. teście brazylijskim.
