Fundamental Study on Stochastic FEM Simulation Considering Variability and Uncertainty due to Molding Process of FRP

Abstract

For heterogeneous material such as fiber reinforced plastic, multiscale computational methods have been used to evaluate the effect of microstructures on the macroscopic properties. Since the variability and uncertainty are involved especially at the microscale due to molding process, there is a growing need for a new stochastic molding and simulation method. This paper presents an example of stochastic finite element simulation considering many random parameters with respect to the distribution of fiber volume fraction in fiber bundles.
