Sažetak
In this contribution, an approach for modelling of ductile damage evolution at microstructural level, represented by a representative sample of material named Representative Volume Element (RVE), is proposed. The nonlocal implicit ductile damage model together with the gradient-enhanced elastoplasticity is employed. A new scale transition procedure between the micro- and macrolevel is derived, where besides the usual homogenization of the stress and constitutive behaviour of a bulk material, particular attention is directed to the consistent upscaling of the damage evolution in the softening regime.
