This paper presents new experimental data of the inelastic behavior of type 316 stainless steel under uniaxially/ multiaxially cyclic loading at elevated temperatures ranging from the room temperature to 650℃. The uniaxial stress-state experiments of tension, creep and ratcheting of isothermal and temperature variation (in-phase/out-of-phase) conditions were Performed. Besides, some multiaxial ratcheting tesis were conducted at several temperatures. In order to describe the inelastic behavior at elevated temperatures, a constitutive model of cyclic viscoplasticity has been presented in the present work. The stress-strain responses calculated by this model agree well with the corresponding experimental results.
