Abstract Three‐point bending tests of the full‐graded concrete under different loading rates were carried out. The cracks quantitatively analyzed by digital image correlation (DIC). toughening mechanism during crack development process was observed, and there are obvious branching aggregate interlocking propagation. At same load level, opening width increases with increase rate. DIC detects a decrease in tortuosity fracture morphology. And at time, damage dam evaluated frequency analysis...
Abstract The dynamic mechanical behavior of concrete has an obvious rate correlation, for this reason, the three‐point bending experiments were carried out on carbon fiber reinforced polymer (CFRP)‐reinforced beam specimens under three different loading rates (0.1, 0.01, 0.001 mm/s). effects damage process, load‐crack mouth opening displacement ( P ‐ CMOD ) curves, and fracture toughness CFRP‐reinforced beams investigated by displacement‐controlled monotonic loading. In addition, acoustic...
Abstract Due to long‐term service, the mechanical properties of pressure pipelines degrade. The cured‐in‐place pipe lining repair technology can strengthen pipelines. repaired with CIPP under reverse fault action need be studied. In this study, finite element (FE) method is used establish a model for pipeline action. And FE evaluated by other literature results. Afterwards, impact some parameters on was analyzed. research results found that as distance and angle slip increase, stress strain...
Abstract In order to investigate the fracture behavior of plain concrete under tensile load, uniaxial test cylinder is carried out in this paper. Acoustic emission (AE) and 3D digital image correlation (3D DIC) are used measure internal acoustic signal surface deformation characteristics specimen. Before stress comes close peak, there very little inside When reaches specimen begins increase dramatically, number microcracks on increases crack width expands gradually. The experimental results...
The fracture properties of engineered cementitious composites (ECC) exposed to dry-wet cycles in sulfate and sulfate-chloride solutions were studied by three-point bending (TPB) beams at the corrosion periods 0, 30, 90, 130, 180, 270, 360 days. digital image correlation (DIC) technique was used understand whole process. toughness energy calculated using proposed method, evolution horizontal strain field, displacement process zone (FPZ) investigated. Meanwhile, compressive tensile performance...
In this paper, the correlation analysis between mechanical fatigue properties and pore structure was performed on self-compacting rubberised concrete (SCRC). Four-point bending destructive non-destructive tests were conducted for obtaining of SCRC, while mercury intrusion porosimetry (MIP) test applied to analysis. Several parameters utilised description structure, including porosity, mean diameter, threshold, fractal dimension, actual minimum diameter most probable diameter. The Pearson...
Compared with traditional cement pastes, geopolymer pastes can effectively alleviate environmental and economic problems caused by the construction industry as they are characterised low carbon dioxide materials, energy reduced consumption emissions. However, mechanical properties of greatly affected composition alkaline activators used in their preparation, existing research results on this influence is not consistent. In study, effects composed varying concentrations sodium hydroxide...
