Elastic Constants of Binary Liquid Crystalline Mixtures
Microscopic expressions for the elastic constants of binary liquid crystalline mixtures composed of short rigid uniaxial molecules are derived in the thermodynamic limit at small distorsions and a small density. Uniaxial and biaxial nematic phases are considered. The expressions involve the one-particle distribution functions and the potential energy of two-body short-range interactions. The th...

that this condition prevailed except for the possibility of ions being trapped in the lattice. An additional electrometer placed in the circuit showed that the trapping probability is (0.2+0 in the energy range over which measurements were made (300—1200 ev). Retarding potentials show that both ion and electron energy distributions are of the order of a few ev; hence small bias potentials are s...

متن کاملIdentification of elastic constants of FCC metals from 2D load-indentation curves
We derive an expression relating the axial load, the indentation depth, and the elastic constants of an orthotropic material, and simplify it to that for a cubic material (e.g., an FCC single crystal). We use this formula and results of three virtual (i.e., numerical) indentation tests on the same specimen oriented differently to find values of the elastic moduli, and show that they agree well ...
متن کاملConstraints on phase stability, defect energies, and elastic constants of metals described by EAM-type potentials.
We demonstrate that the embedded-atom method and related potentials predict many dimensionless properties of simple metals to depend predominantly on a single coefficient μ, which typically lies between 0.3 and 0.45. Among other relations presented in this work, we find that [Formula: see text], [Formula: see text], and [Formula: see text] hold within 25% accuracy and also find a linear depende...
