Abstract: A numerical formulation of the mixed-mode (mode-I and mode-II) fracture in concrete based on the extended fictitious crack model is presented. For crack propagation, the maximum principal stress criterion is used, assuming ...

Abstract: In the past two decades, accidental failure of conical-shaped steel water tanks under hydrostatic pressure has been reported. For safety analysis, the limit analysis of such structures is formulated as a linear programming ...

Abstract: A rigorous analytical procedure for the crack analysis of concrete dams is established using a newly developed numerical technique for analyzing multiple discrete cracks in concrete. The theoretical aspect of the problem ...

Abstract: The discrete crack approach, which has been extensively used for analyzing single cracks, is extended for the numerical analysis of multiple cracks, based on the fictitious crack model and the crack-tip-controlled numerical ...
