Fracture Behavior Characterization of Conventional and High Performance Steel for Bridge Applications
… characterize fracture behavior in the ductile to brittle transition region. In addition, a database of historic bridge fracture toughness data was compiled and re-analyzed using plasticity corrections to estimate elastic-plastic fracture toughness. Correlations between Charpy V-Notch impact energy …

Scale-model investigation of brittle tunnel failure using a true-triaxial device
Brittle instabilities in tunnel excavation have led to severe consequences such as spalling, violent rock ejection or rock burst, and tunnel collapse. Detached rocks from the tunnel boundary not only compromise the structural integrity of tunnels but also pose significant safety risks to personnel …

Uplift capacity of helical piles in thawing permafrost
… axial capacity. The helical pile experiences brittle failures at displacements of about 0.5D for soil temperatures below -2˚C, where D is the helix diameter. Ductile behavior is evident when soil temperature is above -0.2˚C, as the peak load is reached at larger displacements of about 1D. …
