A New Method of Fatigue Life Prediction for Notched Specimen
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.

Strain gradient and electric field gradient effects in piezoelectric cantilever beams
A piezoelectric beam model with strain gradient and electric gradient effects is proposed. An energy variational principle with strain, strain gradient, electric field, and electric field gradient considered as independent variables is postulated to ...

Theory and computation of higher gradient elasticity theories based on action principles [PDF]
In continuum mechanics, there exists a unique theory for elasticity, which includes the first gradient of displacement. The corresponding generalization of elasticity is referred to as strain gradient elasticity or higher gradient theories, where the ...

Gradients of Strain to Increase Strength and Ductility of Magnesium Alloys
A strain gradient was produced in an AZ31B magnesium alloy through a plastic deformation of pure torsion at a torsional speed of π/2 per second. Compared with the base material and with the alloy processed by conventional severe plastic deformation,
