Equivalent Crack, Fracture Size Effect, and Cohesive Stress Zone of Plain Concrete under Quasi-Static and Variable High-Cycle Fatigue Loading
Publisher: American Society of Civil Engineers
Abstract: Compliance-derived equivalent cracks are often used in high-cycle fatigue cracking predictions for computational expediency. Its dependence on the cohesive stress zone, however, may limit general applicability under ...
Prediction of Transient and Steady-State Flexural Fatigue Crack Propagation in Concrete Using a Cyclic R-Curve
Publisher: American Society of Civil Engineers
Abstract: Fatigue damage in plain portland cement concrete is a nonlinear process that exhibits two distinct crack stages: a deceleration stage (transient crack growth) and an acceleration stage (steady-state crack growth). In the ...
