J. Cent. South Univ. (2017) 24: 1676-1683 DOI: 10.1007/s11771-017-3574-x Constitutive model of disturbed soil-structure interface within mining subsidence areas CHANG Hong(常虹)1, 2, XIA Jun-wu(夏军武)1..., the friction angle of the interface decreased as the initial moisture content increased. A constitutive model of the disturbed soil-structure interface, a rigid-plastic model based on the initial......
obtained from experiment, a constitutive relationship model of Ti40 alloy was established by the fuzzy-neural network and compared with the experimental result. The results indicate that the method is feasible to construct a constitutive relationship model for this alloy and high in the degree of fitting, Simultaneously, the complicated nonlinear relationship of thermodynamic parameters can be well......

. The constitutive relationship of Ti-3.0Al-3.7Cr-2.0Fe alloy is obtained on the base of Arrhenius equations. When the strain rates are higher than 0.1 s-1, the dynamic recrystallization occurs in the alloy, and the higher the strain rates are, the more the evident recrystallization is.
