Abstract: Fracture properties for linear elastic fracture mechanics (LEFM), singular-fracture process zone (S-FPZ), and nonsingular-fracture process zone (NS-FPZ) models were determined from the experimental results of three-point ...

Abstract: A direct numerical procedure that extracts the fracture parameters and also predicts fracture responses of concrete fracture specimens is developed. This procedure involves a finite element analysis of the fracture specimen ...

Abstract: A dynamic finite element model, which incorporated a fracture process zone and a maximum tensile stress failure criterion, was used to simulate the results of impact tests on concrete and mortar three‐point bend specimens. ...

Abstract: Nonsingular and singular fracture process zones (FPZ) are used to replicate numerically, dynamic fracture of displacement‐controlled and drop‐weight three‐point bend, concrete specimens and crack‐line wedge‐loaded, ...

Abstract: Finite element models of crack‐line wedge‐loaded, double cantilever beam (CLWL‐DCB) fracture specimens were used in their generation mode to evaluate the crack tip opening displacements (CTOD) associated with a fracture ...

Abstract: Results are reported of a series of tests on concrete crack‐line wedge loaded double cantilever beams. Those tests provide a data base for fracture parameters characterizing mode I cracking in concrete. The development is ...
