Abstract Scope |
Uncertainty quantification (UQ) plays a critical role in verifying and validating forward integrated computational materials engineering (ICME) models. Among numerous ICME models, the crystal plasticity finite element method (CPFEM) is a powerful tool that enables one to assess microstructure-sensitive behaviors and thus, bridge materials structure to performance. Nevertheless, given its nature of constitutive model form and the randomness of microstructures, CPFEM is exposed to both aleatory uncertainty (microstructural variability), as well as epistemic uncertainty (parametric and model-form error). In this work, we discuss several topics in UQ analysis of CPFEM simulations, including forward and inverse UQ problems. In addition, we characterize the effects that various fidelity parameters, such as mesh resolutions, integration time-steps, and constitutive models have in CPFEM with our UQ analysis. |
