Seminar Title: Variational Phase-Field Models of Fracture
Speaker: Blaise Bourdin, A.K. & Shirley Barton Professor of Mathematics, Louisiana State University
Date/Time: October 20, 2020 / 11:00 AM – 12:00 PM
Location: See meeting URL on the cels-seminars website (requires Argonne login)
Host: Stefan Wild
Description: Phase-field models of fracture, which I developed as numerical techniques for Francfort and Marigo’s reformulation of Griffith fracture have become some of the most popular techniques in fracture mechanics. In this talk, I will quickly derive Francfort and Marigo’s variational approach to fracture and its phase-field approximation. I will then discuss their numerical implementation, illustrated with quantitative validation and verification examples on a broad range of applications. Finally, I will discuss recent extensions, the computational challenges that they pose, and the insight they provide on challenging topics such as crack nucleation in quasi-brittle materials and propagation in heterogeneous materials.
