Probabilistic material and component simulation

© Fraunhofer IWM

Many composites, such as those reinforced with short or long fibers or solid foams, have a marked disordered microstructure and, as a result, demonstrate widely varying material behavior. Modern probabilistic simulation methods on the basis of the known variance of microstructural properties can reliably predict the expected variance of material properties. Similarly, a probabilistic component simulation can be used to predict the variance in component behavior on the basis of the variance in material behavior.
