1040 °C was studied during the period imposed 137MPa tensile creep nickel-base single crystal superalloys γ/γ′ the evolution of two-phase approach. ANSYS finite element method is using a single crystal alloy with / without external load when the Von Mises stress in the gand γ′ two phase distribution. The comprehensive analysis of the formula, the coefficient values usually experience, not very accurate,...
By means of measuring creep curves, microstructure observation and FEM analysis of the stress field near the hole; an investigation has been made into the influence of the defects on creep behaviors and microstructure evolution of single crystal nickel-based superalloys. Results show that the creep lifetimes and plasticity of the single crystal nickel based superalloys are obviously decreased by microstructure...
This paper studies the structure-based format to enhance the general principles of ant colony; vanishing moments are given based on structural characteristics of ant colony method. Shows the structure based on ant colony lifting scheme the basic principles of main advantages of ant colony is based on the need of design freedom. Therefore, this problem of vanishing moments for the proposed method for...
Base on the model of dam-foundation dynamic interaction, this paper studied the effect of reservoir on the seismic behavior of concrete arch dam. Three dynamic interaction models were built with the software of ANSYS by means of finite element method. There are interaction models of dam-foundation interaction, dam-foundation-water interaction (Westergaard method) and dam-foundation-water interaction...
