Verification of the ΔKeff hypothesis along the fatigue crack path in thin and thick Al specimens

Julián Andrés Ortiz González, Jaime Tupiassú Pinho de Castro, Giancarlo Luis Gomez Gonzáles, Marco Antonio Meggiolaro, José Luiz de França Freire

Elber assumed that the actual driving force for fatigue crack growth (FCG) is the effective stress intensity factor ΔK_eff. To verify this hypothesis, both DC(T) and C(T) specimens are cut from a 6351-T6 Al alloy circular bar with two…

An investigation of cracks caused by concrete shrinkage and temperature difference in common reinforced concrete bridge structures.

Van-Hau Nguyen

This research investigates cracking in Reinforced Concrete Structures (RCS), particularly in bridge abutments, box girders, and culverts. Cracks often appear even after the concrete has reached its full strength. The current American…
