Imposing equilibrium on measured 3-D stress fields using Hodge decomposition and FFT-based optimization
Hao Zhou, Ricardo A. Lebensohn, Péter Reischig +2
We present a methodology to impose micromechanical constraints, i.e. stress equilibrium at grain and sub-grain scale, to an arbitrary (non-equilibrated) voxelized stress field obta…

The role of slip transfer at grain boundaries in the propagation of microstructurally short fatigue cracks in Ni-based superalloys
M. Jiménez, W. Ludwig, D. Gonzalez +1
Crack initiation and propagation under high-cycle fatigue conditions have been investigated for a polycrystalline Ni-based superalloy by in-situ synchrotron assisted diffraction an…
