Modeling of Manufacturing Uncertainties by Multiscale Approaches

Kreikemeier, Janko and Chrupalla, David (2012) Modeling of Manufacturing Uncertainties by Multiscale Approaches. In: Adaptive, Tolerant + Efficient Composite Structures Research Topics in Aerospace, 1. Springer Verlag. pp. 155-165. ISBN 978-3-642-29189-0.

In this chapter, a numerical multiscale modelling approach is presented and discussed. It bases on the FE2 approach in which a simultaneous finite element computation of the mechanical response at two different length scales is carried out at each macroscopic integration point. The approach is suitable to obtain the global load response of composite structures without omitting the effect of physical phenomena at the local scale, as for example process induced defects like voids or fibre waviness.
