The effect of grain size on the fatigue overload behaviour of nickel
Materials & Design, 2020 The fatigue overload behaviours of coarse grain (~30 μm), ultrafine grain (360 nm) and nanocrystalline (~30 nm) Ni are compared under constant amplitude loading at R = 0.1 after a 100% overload. Synchrotron X-ray diffraction is applied to map the elastic

Interface crack between dissimilar one-dimensional hexagonal quasicrystals with piezoelectric effect [PDF]
, 2019 In this paper, an interface crack between dissimilar one-dimensional (1D) hexagonal quasicrystals with piezoelectric effect under anti-plane shear and in-plane electric loadings is studied. By using integral transform techniques, the mixed boundary value

Experimental Analysis of Displacement Fields around a Crack Tip in Polymers.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1997 Moire interferometry was utilized to determine the displacement fields around a crack tip in single-edge-cracked tensile PMMA and PA6/PPE/SBS alloy specimens. Vertical displacement ν was expressed as a function of the distance γ and the angle θ from a crack tip, and compared with the approximate solution of linear elastic fracture mechanics to study ...

Autonomy and Singularity in Dynamic Fracture
, 2010 The recently developed weakly nonlinear theory of dynamic fracture predicts $1/r$ corrections to the standard asymptotic linear elastic $1/\sqrt{r}$ displacement-gradients, where $r$ is measured from the tip of a tensile crack.
