✦ Synopsis

The reconciliation of finite element (FE) analysis with vibration test data is a field of research which has generated considerable interest over the past decade. However, the intermediate, and perhaps most crucial phase of locating modelling errors has received relatively little attention. This paper proposes a new technique for error location in FE models based on the force balance approach. The method differs from some current approaches in that it does not assume that regions of response error are necessarily an indication of modelling error. Co-ordinate completeness is achieved by an appropriate choice of data expansion technique which is chosen specifically to suppress measurement noise. The success of the method is demonstrated by means of a simulated case study.

A new nonconforming exponentially fitted finite element for a Galerkin approximation of convectiondiffusion equations with a dominating advective term is considered. The attention is here focused on the drift-diffusion current continuity equations in semiconductor device modeling. The scheme extends

For two-dimensional solids the multiregion concept and the time-domain approach in the boundary element method are employed to model cracks in transient dynamics. The propagation of cracks and the closing and opening of crack sides are simulated by disconnecting and connecting degrees of freedom of
