A microstructure based fatigue life prediction framework and its validation
… in concert like the elastic stress anisotropy, plastic strain accumulation, resolved shear stress, normal stress, slip-system length, and grain boundary character. In nickel-base superalloys, fatigue cracks tend to initiate near twin boundaries. The factors causing fatigue crack initiation …

Quantitative understanding of the role of grain boundaries in polycrystalline deformation via multiscale digital image correlation
… image correlation (DIC) was used to measure plastic strain accumulation in polycrystalline Hastelloy X, a nickel-based superalloy, subjected to monotonic and cyclic loading conditions. In addition, the underlying microstructure was characterized with similar spatial resolution using electron …

Critical stresses for twinning, slip and transformation in shape memory alloys: modeling and experiments
… slip stress, and hence the possibility of any plastic strain accumulation is minimized. Overall, we find that higher alloying content exhibits higher difference between the austenite slip and the transformation stress, exhibiting better shape memory performance. The other class of alloys we …
