Abstract Scope |
The microstructure-sensitive prediction of transverse failure strength in unidirectional polymer matrix composites (PMCs) remains elusive. This is mainly due to difficulties in quantifying the stochasticity in PMC microstructures, which propagates into variable damage property predictions. Traditionally, finite-element (FE) simulations have been used to extract microstructure-sensitive properties over representative volume elements of the material. However, the computational cost of running FE simulations can be incredibly high, especially when a large number of evaluations are needed to quantify stochasticity in the material response and characterize relevant properties. Statistical machine learning tools such as continuous normalizing flows are well suited for addressing this challenge, as they enable rapid microstructure to property predictions and perform efficient and exact inference of arbitrarily complex densities. This talk will discuss the advantages of using continuous normalizing flows in the context modeling PMC damage resilience, as well as demonstrate their efficacy in extracting microstructure-damage resilience property relationships. |
