This project focuses on developing a framework that would allow us to estimate the fracture toughness of any alloy using a non-destructive approach. Estimating plastic properties such as fracture toughness is currently impossible due to the elastic nature of NDE methods. Existing work focuses on correlations using a large number of experiments, which are very specific to a given alloy and heat treatment, severely limiting the approach. This project aims to utilize a combination of linear and nonlinear techniques to estimate microstructural parameters that will be used as inputs for a crystal plasticity finite element (CPFE) model to capture both elastic and plastic properties of the material, thus allowing us to estimate the fracture toughness.
