Abstract:The structures and elastic constants of fcc structure nickel at high temperature have been calculated by using molecular dynamic simulations with the direct method and the quantum Sutton-Chen (Q-SC) potential. The obtained lattice constants, linear thermal expansion coefficients, thermoelastic constants are in excellent agreement with the available experimental data. The calculated results for the radial distribution function showed that the short-range atomic order of low-T is similar to the high-T solid. The thermoelastic constants, bulk modulus and shear modulus as a function of the applied temperature are presented. An analysis for the calculated parameters has been made to reveal mechanical stability of nickel up to 1300 K. | |||

Abstract:The problem of phase change about ice and water was solved in the structured meshes by using moving heat source method, which is a representative of many industrial processes. The temperature field was also studied by discrete source term. The single and bilateral region problems were given to demonstrate the correctness of this method; the results are agreement when the numerical solution was compared with the exact solution. These demonstrate feasibility of the numerical calculation fully, as well as its application in industry to provide useful information. | |||

Abstract:An analytical solution has been developed from the perspective of local bond average to correlating the elastic modulus of a specimen to the length and strength of the representative bonds and their response to temperature change. It is showed that the elastic weakening arises from the bond length expansion and the bond strength weakening by raising the inner energy. Reproduction of the measured temperature dependence of the elastic modulus of solid Ag, Au, MgO, Mg2SO4, Al2O3, and KCl specimens has led to information about the mean atomic cohesive energy of the specimens, which goes beyond the scope of available approaches. | |||
