A New Method of Fatigue Life Prediction for Notched Specimen
Journal of Aeronautical Materials, 2017 The simulations of the notched specimens under multiaxial loading were conducted by finite element method. The simulation results show that the stress gradient increases with the decrease in notch radius for the same strain path.

A theory of strain-gradient plasticity with effect of internal microforce [PDF]
Theoretical and Applied Mechanics, 2017 This paper develops a theory of strain gradient plasticity for isotropic bodies undergoing small deformation in the absence of plastic spin. The proposed theory is based on a system of microstresses which include a microstress vector consistent with ...
