Fracture under body forces: An accessible test and analysis
Farhad Kamarei, Sarah Bueno De Castro, Jeffery R. Roesler +1
Fracture in large-scale structures --- from failing concrete dams to calving glaciers --- is dominated by self-weight. Yet, owing to their immense scale, directly studying when and…
A Guide to Fully Characterize the Fracture Properties of Cementitious Materials from Simple Experiments
Subhrangsu Saha, Bruce J. Moore, Ben Manaugh +2
Guided by recent advances in the understanding of nucleation and propagation of fracture in elastic brittle materials, this paper proposes a suite of three simple experiments that…
Breaking Four-Point and Three-Point Bending Tests
Subhrangsu Saha, Jeffery R. Roesler, Oscar Lopez-Pamies
Since their initial standardizations in the 1930s and 1950s, the so-called four-point and three-point bending tests on unnotched beams have been embraced by practitioners as two po…
Automatic joint damage quantification using computer vision and deep learning
Quang Tran, Jeffery R. Roesler
Joint raveled or spalled damage (henceforth called joint damage) can affect the safety and long-term performance of concrete pavements. It is important to assess and quantify the j…
