A continuous and discontinuous modelling approach was used. Using a continuous approach, numerical analyses were performed using a finite element method and three different enhanced continuum models: isotropic elasto-plastic, isotropic damage and anisotropic smeared crack one. The models were equipped with a characteristic length of micro-structure by means of a non-local and a second-gradient theory. So they could properly describe the formation of localized zones with a certain thickness and spacing and a related deterministic size effect. Using a discontinuous FE approach, numerical results of cracks using a cohesive crack model and XFEM were presented which were also properly regularized. Finite element analyses were performed with concrete elements under monotonic uniaxial compression, uniaxial tension, bending and shear-extension. Concrete beams under cyclic loading were also simulated using a coupled elasto-plastic-damage approach. Numerical simulations were performed at macro- and meso-level of concrete. A stochastic and deterministic size effect was carefully investigated. In the case of reinforced concrete specimens, FE calculations were carried out with bars, slender and short beams, columns, corbels and tanks. Tensile and shear failure mechanisms were studied. Numerical results were compared with results from corresponding own and known in the scientific literature laboratory and full-scale tests.    . 410 0$aSpringer Series in Geomechanics and Geoengineering,$x1866-8755 606 $aConcrete construction$xMathematical models 606 $aStructural analysis (Engineering)$xMathematical models 606 $aFinite element method 615 0$aConcrete construction$xMathematical models. 615 0$aStructural analysis (Engineering)$xMathematical models. 615 0$aFinite element method. 676 $a624.15136 700 $aTejchman$b Jacek$01064940 701 $aBobiski$b Jerzy$01763092 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910437762903321 996 $aContinuous and discontinuous modelling of fracture in concrete using FEM$94203349 997 $aUNINA
