Abstract To overcome the harsh experimental conditions of determining the mode-II critical energy release rate GIIC,
a flexible experiment-simulation method for determining GIIC is proposed based on the mixed-mode fracture
experiments and the corresponding simulations by the mixed-mode phase-field model. In details, a mixedmode fracture experiment is first conducted to obtain the initial crack deflection angle. Subsequently, a
series of phase-field simulations are conducted by altering the value of GIC/GIIC to reproduce the
experimental result so as to determine the value of GIIC with a known GIC. Three mixed-mode fracture tests
(single edge cracked circular test, central crack rectangular tension test… More >
