Finite element analysis

Dimensioning and calculation of composite components using FE analysis

The analysis of rigidities and strengths of fiber reinforced plastics to be expected is a complex technical task. Calculating engineers entrusted with it must have comprehensive theoretical knowledge and years of experience. At TEUFELBERGER, we have a team of specialists who handle such tasks and, in doing so, combine state-of-the-art calculation software with an extensive database for characteristic values of various fiber and resin systems. 

The finite element method can be used to simulate characteristics of components which otherwise can only be determined in costly destructive testing procedures.  This helps save a lot of time and money.
For materials with non-direction-dependent properties (e.g., metals), this task is still relatively easy to solve by relying on proven methods.  However, the finite element analysis of fiber reinforced plastics with greatly direction-dependent properties and numerous fiber matrix combination options still is a relatively recent scientific development. Especially where the simulation of the properties of complex fiber orientations (e.g., braided structures) is concerned, different scientific approaches will yield different results.

At TEUFELBERGER, the many years of expertise in processing different composite fibers (carbon fibers, glass fibers, etc.) and the material cards derived from a large number of characteristic value samples are always incorporated into the calculation approach.
Where structural analysis is concerned, we work with ANSYS software which puts us in a position to realistically predict the behavior under certain load specifications, even for complex assemblies.   

In this process, it is possible to individually deal with installation space specifications, target weights, rigidity requirements, and partly also with the fiber/matrix failure behavior. Based on such FE analysis, our customers get a detailed concept for the design of the fiber reinforced plastic component. Subsequently, we derive from it the suitable manufacturing concept and the manufacturing costs. Hence, each step in the product creation process can be visualized for our customers in a non-ambiguous and transparent format.
