Abstract: Interfacial adhesive bonding of concrete-like materials is strengthened by short Kevlar fibers. The tough and flexible Kevlar fibers, bridging across grain structures, can effectively suppress premature surface and subsurface ...

Abstract: Size effect (SE) on quasi-brittle fracture of concrete and concretelike heterogeneous materials has been commonly demonstrated by the influence of specimen size

Abstract: A multicutting technique is introduced, which can be used to determine the extension of the fracture‐process zone together with the conventional compliance method. A new compliance curve is established from a damaged ...

Abstract: Crack tip shielding due to crack-interface bridging in a cellulose fiber reinforced cement, plain mortar and a coarse-grained alumina is studied in terms of a novel compliance function φ-curve ...

Abstract: Mortar, as concrete-like coarse-structured materials, has a fracture process zone ahead of crack tip after the crack initiation. The maximum fracture load must be related to the cohesive crack-tip local fracture energy due ...

Abstract: Depending on the relevant material properties, failure of grouted anchors can take forms of pullout of concrete cones, debonding at either anchor–grout or grout–concrete interface, fracture of anchor and combination of ...

Abstract: Depending on the relevant material properties, failure of grouted anchor anchorage to concrete can result from pullout of concrete cones, debonding at either anchor-grout or grout-concrete interface, fracture of anchor, ...

Abstract: Fiber-reinforced polymer (FRP) composite materials have been widely used in the field of retrofitting. Theoretical analysis of FRP plate- or sheet-strengthened cracked concrete beams is necessary for estimating service ...
