Abstract
-
A state variable constitutive equation that can be solved for the state variables, can then be used to calculate the state variable histories from the stress and strain histories observed during an experiment. This was done using the Bodner Partom flow equation for cast and wrought Rene 95 at 650 C. The evolution equation was determined for a state variable that characterizes the resistance to plastic flow and some properties of a damage state variable were established. Analysis of the tensile and creep data strongly suggested that two different mechnisms were active during deformation. A limited number of experimental results were compared to the response calculated from the flow and evolution equations.
