GRADIENT DAMAGE WITH VOLUMETRIC-DEVIATORIC DECOMPOSITION AND ONE STRAIN MEASURE
Keywords:
isotropic damage, gradient enhancement, finite element methodAbstract
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.Downloads
