Probabilistic material and component simulation

© Fraunhofer IWM

Many composites, such as short or long fiber reinforced plastics or solid foams, have a distinctively disordered microstructure and, as a result, exhibit a scattering, uncertain material response. Modern probabilistic simulation methods based on the known variance of microstructural properties can predict the expected variance of material properties in a reliable manner. Similarly, a probabilistic component simulation can be used to predict the variance in component behavior based on the variance in material behavior.
