Numerical analysis of reinforced concrete continuous deep beams

The structural behaviour of deep beams is still not completely understood, since, for example, plane sections do not remain plane and no uniform shear flow can develop because of the small ratio between depth and shear span. If in addition, the supporting system is also statically indeterminate, the number of difficulties increases. In order to...

FEM modelling of elastoplastic stress and strain field in centre-cracked plate

Finite element procedure for modelling fibre metal laminates

Two approaches for the analysis of masonry structures: Micro and macro-modeling

Two models for the micro- and macro-analysis of masonry structures are presented. For the micromodeling of masonry, an interface failure criterion that includes a straight tension cut-off, the Coulomb friction law and an elliptical cap is proposed. The inelastic behavior includes tensile strength softening, cohesion softening, compressive...

Fundamental issues in finite element analyses of localization of deformation

A non-linear finite element approach for the analysis of mode-I free edge delamination in composites

Aspects of Robust Computational Modeling for Plain and Reinforced Concrete

The problems commonly encountered in the numerical analysis of reinforced structures are often related to biaxial stress states in the structure. In this study this problem is solved with the formulation of a composite plasticity model which describes both cracking and crushing of concrete within the framework of plasticity theory. The other...
