A cost-efficient potential for light weight construction is offered by the use of hybrid materials or components. Moreover, hybrid components may create a technical advantage.
The article presents a systematic approach, based on an analytical model, for the development of a hybrid component. This approach is illustrated at the example of a hybrid construction designed for an elastic performance. First an abstraction of the components geometry is done by introducing a model of a simple bending beam. Analytical solutions for centrically acting perpendicular forces are presented for this simple model. The impact of bearings on the elastic performance of the construction is discussed on the basis of bearing stiffness.
Alternatively, the results will be replicated by means of a finite element method (FEM). Further development is solely based on this numerical model and will be extended by an additional lateral force. The impact of the component cross section on the performance is presented by using variable dimensions. The aim of this work is a substantiated proposal of an appropriate material selection based on adequate component understanding by the analysis of the components function. In this process the material selection rest on the storable elastic energy, which mainly depends on the specific Young’s modulus.
