Precipitate-Domain Wall Topologies in Hardened Li-doped NaNbO3
TL;DR: In this paper , the topology of the precipitate-domain wall assembly was clarified, revealing a full pinning on the domain walls by the incorporated plate-like precipitates, which provides a fundamental basis for future optimization strategies for platelet hardening in new lead-free piezoceramics for high-power applications.

Computational Homogenization of Piezoelectric Materials using FE2
TL;DR: In this paper, a two-scale classical (first-order) homogenization of electro-mechanically coupled problems using a FE2-approach is discussed, explicitly formulated the homogenized coefficients of the elastic, piezoelectric and dielectric tensors for small strain as well as the homogeneized remanent strain and remanent polarization.
