Crack pattern in ceramics subject to thermal shock

Phase field models of dynamic fracture

Accounting for inertial effects in phase-field modes of fracture.

While the mathematics community has mostly focused on rate-independent (quasi-static) models for fracture, many engineering and industrial application involve dynamic effects. In collaboration with Christopher J. Larsen, Christoph Ortner, and Endre Süli, (Bourdin, Larsen, & Richardson, 2011), (Larsen, Ortner, & Süli, 2010), I have extended phase-field models of fracture to the dynamic setting, and developed the staggered scheme later used in (Borden, Verhoosel, Scott, Hughes, & Landis, 2012), (missing reference):

Numerical simulation of an antiplane shear fracture experiment. At high enough loading rates, cracks branch and kink, as expected.
