DOI: 10.1016/j.engfracmech.2020.107054
Abstract: Abstract An analytical model of fracture process zone (FPZ) was proposed to explore the intrinsic meaning of the “constant crack-tip opening angle (CTOA)” fracture criterion. A relationship between critical CTOA and the essential work of… read more here.

DOI: 10.1016/j.engfracmech.2021.107606
Abstract: Abstract Since concrete infrastructure may lose its expected physical and functional properties over time, accurate inspection and assessment of such infrastructure systems is necessary to ensure safety and serviceability and prevent unsafe working conditions and… read more here.

DOI: 10.1016/j.ijsolstr.2018.12.019
Abstract: Abstract Failure in brittle rock happens because micro-cracks in the crystal structure coalesce and form a localized fracture. The propagation of the fracture is in turn strongly influenced by dissipation in the fracture process zone.… read more here.

DOI: 10.1520/jte20180863
Abstract: The fracture process zone (FPZ) of concrete under three-point bending was extensively investigated using the digital image correlation technique. Surface displacement, strain components, crack opening displacement, effective crack length, and crack tip position were calculated… read more here.
