Rotational instability of the electric polarization and divergence of the shear elastic compliance
F. Cordero, H. T. Langhammer, T. Müller +2
The rotational instability of the electric polarization P during phase transformations between ferroelectric phases is of great practical interest, since it may be accompanied by e…
Broadband dielectric spectroscopy of Ba(Zr,Ti)O3: dynamics of relaxors and diffuse ferroelectrics
J. Petzelt, D. Nuzhnyy, M. Savinov +6
Broadband dielectric spectroscopy from Hz up to the infrared (IR) range and temperature interval 10-300 K was carried out for xBaZrO3-(1-x)BaTiO3 (BZT-x, x = 0.6, 0.7, 0.8) solid s…
Dislocation mutual interactions mediated by mobile impurities and the conditions for plastic instabilities
Fabio Leoni, Stefano Zapperi
Matallic alloys, such as Al or Cu, or mild steel, display plastic instabilities in a well defined range of temperatures and deformation rates, a phenomenon known as the Portevin-Le…
Avalanches in 2D Dislocation Systems: Plastic Yielding is not Depinning
Péter Dusán Ispánovity, Lasse Laurson, Michael Zaiser +3
We study the properties of strain bursts (dislocation avalanches) occurring in two-dimensional discrete dislocation dynamics models under quasistatic stress-controlled loading. Con…
Optimal Energy Dissipation in Sliding Friction Simulations
A. Benassi, A. Vanossi, G. E. Santoro +1
Non-equilibrium molecular dynamics simulations, of crucial importance in sliding friction, are hampered by arbitrariness and uncertainties in the removal of the frictionally genera…
