Acta Physica Sinica, 1958 In the recent years, the theory related to friction-lines has been independently developed both in Europe and here, according the information reached the author in 1956. These investigations are based on the condition of least frictional resistance at a point.In 1954, a variational equation (2a) on classical basis was given on a meeting for the related

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
