Comparative study on the fatigue behaviour of SCC and VC [PDF]

open access: yes, 2014
Continuous cyclic loading on concrete constructions involves a progressive cracking mechanism, leading to significant changes of the material properties during the lifetime of the structure.

Factors effecting the recovery process of self-repairing concrete

open access: yesИнженерно-строительный журнал, 2019
In order to explore the influence of external environmental factors, the initial width of cracks and the placement of glass fiber tubes on the repairing effect of self-repairing concrete, glass fiber tubes are built in self-repairing concrete specimens ...

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]

open access: yes, 2007
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

A Unified Formula for Calculation of Crack Width and Spacing in Reinforced Concrete Beams

open access: yesInternational Journal of Concrete Structures and Materials, 2021
Highlights Reinforced concrete beam cracking behavior was experimentally examined with a new type of seismic bar. New methods for the calculation of average crack spacing and maximum crack width were presented.

Chloride Diffusivity and Life Prediction of Cracked RC Beams Exposed to Different Wet-Dry Ratios and Exposure Duration

open access: yesAdvances in Materials Science and Engineering, 2017
Effects of crack width, wet-dry ratio, and exposure duration of wet-dry cycles on chloride ingress of RC beams were experimentally studied. Crack widths of 40, 70, 90, and 120 microns were, respectively, induced by three-point flexural loading and four ...

Experimental Study on Crack Width of HRB600 Grade High-Strength Steel Bar Reinforced Concrete Beams

open access: yesBuildings, 2023
High-strength reinforcement is an important direction in the development of civil engineering. In order to fill the gap that the current concrete structure code GB50010 has no standard regulations applicable to HRB600-grade high-strength reinforcement ...

Oscillatory fracture path in thin elastic sheet [PDF]

open access: yes, 2003
We report a novel mode of oscillatory crack propagation when a cutting tip is driven through a thin brittle polymer film. The phenomenon is so robust that it can easily be reproduced at hand (using CD packaging material for example).
