Numerical and experimental investigation of mixed‐mode crack growth in aluminum alloys
Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 10, Page 2854-2872, October 2022., 2022 Abstract Fatigue crack growth in Al 2024 and Al 7050 specimens was assessed experimentally and numerically. In the experimental investigation, various specimen configurations and loading conditions were used to achieve pure mode I, pure mode II, and mixed mode I/II, I/III, and I/II/III.

Numerical Simulation of Fracture Behavior of Brittle Solids under I/III Loading
Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 This study used numerical analysis to carry out a large number of numerical model calculations based on a new semicircular bend (SCB) model. Instead of existing numerical computation methods (J‐integral), the M‐integral method was used to calculate the mixed mode fracture parameters (KI, KII, and KIII), investigate the influence of the geometry and ...
