Phase Field Fracture Simulation Assessment

Project: Research project

Project Details

Description

Fracture is a particularly insidious failure mode of a material. Many phase field methods have been proposed to compute crack nucleation and propagation. These methods have the advantages of not requiring the path of the crack to be known a priori, accurately capturing the driving force for crack growth, and the ability to include the complications of the microstructures seen in engineering materials such as grains and precipitates in the calculation. To use any of these models confidently in the design of a material requires a more quantitative assessment of the veracity of these models. We thus propose to develop a quantitative assessment methodology for these phase field fracture simulation tools by comparing the calculated crack paths to those measured using state-of-the-art X-ray tomography. The goal is to produce a verified and validated model of the fracture of engineering materials.
