Plastic strain gradients and transient fatigue crack growth: A computational study
International Journal of Fatigue(2019)
摘要
•Plastic strain gradients restrict crack-tip plasticity during an overload.•Restricted plastic deformation enhances post-overload crack growth rates.•Plastic strain gradients are key in the evolution of post-overload crack closure.•Plastic strain gradients do not affect steady-state fatigue crack growth rates.
