Abstract

In the design of laminated composites it is necessary to define a large number of design variables and manifold objective functions or multicriteria objective functions. The question is: are we able to solve all the arising problems economically on the FEM-level, or should we split some tasks so that we can handle them on a local sublevel (fig.1)? The advantage is that we can reduce the effort significantly when operating on a sublevel; the weak point is, however, the definition of FEM-level-corresponding constraints and the design of corresponding objective functions. This means we try to introduce decoupling conditions between the FEM- and local level of optimisation. The analysis procedure on the local level may be defined according to the used elements, the aspect ratio or the location of the load measurement points.
