Because a rigorous bending theory for thin shells of revolution is complicated, attempts have been made for reliable approximations of the edge disturbance problem under axisymmetric loading. A well-known one was published by Geckeler [1, 2], who obtained his approximation by mathematical considerations. He started from kinematic,...

Donnell published in 1933 an elegant and rather simple differential equation for the stress analysis in circular cylindrical shells. The civil engineering structural mechanics group in Delft has a long and strong experience in the fifties and sixties of last century in working with this shell equation in close cooperation with the then...

The present paper describes a numerical formulation for the analysis of damage in steel pipeline bends. In particular, the numerical implementation of Gurson plasticity model is described in the framework of a special element, referred to as “tube element”. This is a three-node element, which simulates pipe behavior combining longitudinal...

In the sixties Prof. J. Witteveen introduced a discrete model for the elastic analysis of slabs (Heron 1966). This article presents a similar approach for the design of reinforced concrete walls and deep beams, with holes or otherwise. The model – which is called stringer-panel model – combines the advantages of the popular strut-and-tie method...

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...

Numerical tools to simulate cracking in concrete and similar materials are developed. Firstly, a treatment is given of smeared and discrete crack concepts, which start from the notion of a continuum and a discontinuum respectively. With the smeared crack concept a distinction is furthermore made between fixed, multi-directional and rotating...

The theory of elasticity has been a well-established domain of engineering science for over a century, and solutions exist for many particular problems. It is not the aim of this contribution to extend the scope of the theory, but instead to draw attention to a specific way to formulate problems. So this contribution touches upon didactics in...

The possibilities of the smeared crack concept for simulating crack propagation and fracture in concrete is investigated. A smeared crack formulation is proposed which treats concrete constitutive behaviour separately from crack interface behaviour. In this study concrete is in most cases modelled as having linearly elastic characteristics. For...

It is becoming increasingly necessary to investigate the strength of reinforced concrete structures subjected to dynamic loading. Experience and knowledge relating to the non-linear dynamic behaviour of such structures is still limited, however. Attempts to solve this type of problems with the aid ofa finite element approach soon encounter...
