Abstract

This paper deals with the problem of a through‐cracked tubular joint behaviour modelling. A new beam finite element has been created, in order to take into account the loss of stiffness of the joint due to through‐thickness crack presence, and the coupling between axial force and bending momentum. This allows to study at a low computing time large damaged offshore structures, using beam elements. The mechanical model used to build the finite element is first described. An analytical identification of its internal parameters (eccentricity and stiffness) is then performed. Finally, some results are presented. Copyright Β© 2002 John Wiley & Sons, Ltd.

## Abstract A model which allows the introduction of displacements jumps to conventional finite elements is developed. The path of the discontinuity is completely independent of the mesh structure.

Perfectly matched anisotropic absorbers are introduced in two-and three-dimensional beam propagation methods. The anisotropic perfectly matched layer does not require the modification of Maxwell's equations, and can be easily implemented in codes which deal with anisotropic materials. Finite-element
