effect of viscoplastic relations on the instability strain shear Band initiation strain the strain corresponding to the minimum shear Band spacing and the Band Width in a thermoviscoplastic material
International Journal of Plasticity, 2001Co-Authors: R C BatraAbstract:We study thermomechanical deformations of a steel block deformed in simple shear and model the thermoviscoplastic response of the material by four different relations. We use the perturbation method to analyze the stability of a homogeneous solution of the governing equations. The smallest value of the average strain for which the perturbed homogeneous solution becomes unstable is called the critical strain or the instability strain. For each one of the four viscoplastic relations, we investigate the dependence upon the nominal strain-rate of the critical strain, the shear Band initiation strain, the shear Band spacing and the Band Width. It is found that the qualitative responses predicted by the Wright–Batra, Johnson–Cook and the power law relations are similar but these differ from that predicted by the Bodner–Partom relation. The computed Band Width is found to depend upon the specimen height. # 2001 Elsevier Science Ltd. All rights reserved.

Anomalous electrical resistivity and Hall constant of Anderson lattice with finite f-Band Width
2002Co-Authors: S. Panwar, I. SinghAbstract:We study here an extension of the periodic Anderson model by considering finite f-Band Width. A variational method is used to study the temperature dependence of electronic transport properties of Anderson lattice for different values of the f-Band Width. The electrical resistivity ρ(T) and Hall constant R H (T) calculated show qualitatively the features experimentally observed in heavy fermion materials. We find that as f-Band Width increases, the low temperature peak in ρ(T) disappears. while the low-temperature peak in R H (T) becomes sharper.

Magnetic Susceptibility of the Anderson Lattice with Finite f-Band Width
physica status solidi (b), 1995Co-Authors: S. Panwar, I. SinghAbstract:An extension of the periodic Anderson model by considering the finite f-Band Width is considered. A variational method is used to study the temperature dependence of the valence n f and of the magnetic susceptibility X s for various values of f-Band Width. As the f-Band Width is reduced, the low temperature peak in the susceptibility X s gets sharpened.

Magnetic susceptibility and electronic specific heat of Anderson lattice with finite f‐Band Width
Journal of Applied Physics, 1994Co-Authors: S. Panwar, I. SinghAbstract:We study an extension of the periodic Anderson model by considering finite f‐Band Width. A variational method recently developed, has been used to study the temperature dependence of the average valence of magnetic susceptibility χs and electronic specific heat Cv for different values of the f‐Band Width. As f‐Band Width increases, the low‐temperature peak in χs and Cv becomes more broad and shifts towards the high‐temperature region.

ELECTRONIC SPECIFIC HEAT AND THERMOELECTRIC POWER OF AN ANDERSON LATTICE WITH FINITE F-Band Width
Physical review. B Condensed matter, 1994Co-Authors: S. Panwar, I. SinghAbstract:We study here an extension of the periodic Anderson model by considering finite [ital f]-Band Width. A variational method recently developed by us has been used to study the temperature dependence of the electronic specific heat [ital C] and the thermoelectric power [ital Q] for different values of the [ital f]-Band Width. We find that as the [ital f]-Band Width increases, the low-temperature peak in [ital C] becomes broader and shifts toward the high-temperature region, while the low-temperature peak in [ital Q] becomes sharper and shifts toward the low-temperature region and disappears for still larger values of the [ital f]-Band Width.

Recursion equations in predicting Band Width under gradient elution.
Journal of Chromatography A, 2004Co-Authors: Heng LiangAbstract:The evolution of solute zone under gradient elution is a typical problem of non-linear continuity equation since the local diffusion coefficient and local migration velocity of the mass cells of solute zones are the functions of position and time due to space- and time-variable mobile phase composition. In this paper, based on the mesoscopic approaches (Lagrangian description, the continuity theory and the local equilibrium assumption), the evolution of solute zones in space- and time-dependent fields is described by the iterative addition of local probability density of the mass cells of solute zones. Furthermore, on macroscopic levels, the recursion equations have been proposed to simulate zone migration and spreading in reversed-phase high-performance liquid chromatography (RP-HPLC) through directly relating local retention factor and local diffusion coefficient to local mobile phase concentration. This new approach differs entirely from the traditional theories on plate concept with Eulerian description, since Band Width recursion equation is actually the accumulation of local diffusion coefficients of solute zones to discrete-time slices. Recursion equations and literature equations were used in dealing with same experimental data in RP-HPLC, and the comparison results show that the recursion equations can accurately predict Band Width under gradient elution.

CARS difference spectroscopy. II—Determination of small frequency shifts and Band Width changes in binary mixtures
Journal of Raman Spectroscopy, 1992Co-Authors: A. Weippert, W. KieferAbstract:The experimental verification of CARS difference spectroscopy (CARS-DS) is presented and its application to binary mixtures is shown. The experimental set-up allows the simultaneous measurement of CARS spectra of two different samples under identical conditions. It is shown how the method can be used for the accurate determination of small frequency shifts and Band Width changes in liquid mixtures. The experimental spectra obtained were analysed by their numerical simulation using a least-squares fitting routine. As examples, experimental results for chloroform–deuterochloroform isotopic mixtures and binary mixtures of benzene and toluene of different concentrations are presented. In both cases frequency shifts and changes in the Band Width were observed which exhibit an almost linear dependence on the mole fraction of the probe species.
