Representation of Time Dependent Mechanical Behavior of Rene 95 by Constitutive Equations

摘要

The constitutive equations of Bodner-Partom are utilized to represent the time dependent inelastic properties of Rene 95 at 1200 F (649 C) over a wide range of uniaxial loading conditions. These include controlled monotonic straining, creep, stress relaxation, and cyclic loading. The material constants are obtained from a few test points and are used to calculate response characteristics which are compared to corresponding test results. Some general conclusions on the inelastic behavior of Rene 95 are discussed. (Author)
