Microcracks in concrete can coalesce into larger cracks that further propagate under repetitive load cycles. Complex process of crack formation and growth are essentially involved in the failure mechanism of concrete. Understanding the crack formation an...

A novel finite element model is proposed to simulate reinforced concrete (RC) beams strengthened in shear by carbon fibre-reinforced polymer (CFRP) plate under cyclic loading. A spring element is developed to simulate the fracture zone based on the virtu...

In this paper, we experiment on the hydraulic fracturing of asphalt concrete with a voids content higher than 3%, which has arisen from the possible local shear dilatancy of Quxue asphalt?s core wall of concrete core dam, the highest one of the sort cons...

Shear crack analysis is essential for engineers to estimate repair work in concrete structures. So far, conventional theoretical and numerical analyses in fracture mechanics have been applied to study concrete flexural beams, but there is still lit...
