    Homogenisation of composite materials using global optimisation

  • Original language description

    This paper introduces a method for creating a homogenous substitute material for composite materials using optimisation algorithms during an inversion task. Numerical modelling of composite materials is, due to its multi-layer structure and loss properties of each individual layer, very difficult to compute. This multi-layer structure and loss characteristics of the composite model are represented, in the numerical simulators, as a very fine grid, resulting in an extremely high density of mesh-cells andmaking the simulation time much longer and the calculation much more complex. By numerical modelling of composite aircraft, the intension was to replace the composite material with a homogenous substitute material having equivalent behaviour to that ofthe composite material in an electromagnetic field. This homogenous substitute material is then represented by a much less detailed grid than the original composite, thus reducing computing time and hardware demands.
