We no longer use wind-up smartphones because no materials have a high enough elastic limit to store elastic energy with a high enough energy density. The elasticity of a material determines its capacity to transmit energy in this form. The amount of energy stored in the spring is determined ...
potential energy functions/ elastic constantspair potentialsnematogenic lattice modelsDirector configurations in nematic liquid crystals can be determined by minimizing their elastic free-energy density, on the basis of elastic constants and of specific boundary conditions; in some published cases, this has...
On the other hand, we can construct, in different ways, a lattice model with pairwise additive interactions, which approximately reproduces the elastic free energy density, where the parameters defining the pair potential are expressed as linear combinations of elastic constants. An anisotropic nemato...
The BK model calculates the macroscopic strain energy density U in the alloy. (64)U=∑ij∫σijdεij Finding an extremum of the macroscopic strain density U for the volume fraction of the carbide phase under modified rules of mixture (62) and (63) allows the BK model to calculate the e...
This work compares the performance of traditional phenomelogical Woods-Saxon (WS) and squared WS (SWS) potentials with that of a non-monotonic (NM) potential, microscopically derived using the energy-density functional (EDF) formalism from a realistic two-nucleon potential that includes the Pauli ...
This work is based on a weighted density functional formalism developed by us in a previous paper (Singh et al 1992 Phys. Rev. A 30 583). A brief summary of the status of theoretical development for the elastic constants of nematics is presented. Considering a pair potential having both ...

A plot of the ratio of surface energy density at pull-off to surface energy density from LJ potential \({\gamma }^{eff}/\gamma \) with respect to \(\gamma /{E}^{\ast }{g}_{N}{({h{\prime} }_{rms})}^{m}\) for various values of slopes. The data in this plot is compute...
Thermal properties such as the lattice thermal conductivity, thermal relaxation time, crystal energy density, and acoustic coupling constant were computed at different temperatures and along various directions. The longitudinal and shear components of ultrasonic attenuation were evaluated along the three ...
