Shack-Hartmann wavefront sensing: A new approach to time-resolved measurement of stress intensity during dynamic fracture of small brittle specimens
Liuchi Li, Velat Kilic, Milad Alemohammad +3
The stress intensity factor is important for understanding crack initiation and propagation. Because it cannot be measured directly, the characterization of the stress intensity fa…

Meso-scale size effects of material heterogeneities on crack propagation in brittle solids: Perspectives from phase-field simulations
Liuchi Li, Jack Rao, Todd Hufnagel +1
Brittle solids are often toughened by adding a second-phase material. This practice often results in composites with material heterogeneities on the meso scale: large compared to t…
