The areas of study include: (1) a state variable approach to the analysis of transient creep deformation in stress reduction experiments; (2) a detailed study of the strain aging behavior of 316 stainless steel at room temperature; (3) a review of machine design, instrumentation and data analysis techniques for conventional mechanical testing at elevated strain rates; (4) a study of grain boundary sliding behavior and related deformation phenomena in Incoloy 800H at elevated temperatures; and (5) a review of progress in analytical and numerical research on the finite element modeling of non-elastic deformation processes using state variable constitutive laws. In general a state variable approach has been taken in developing a description of the deformation phenomena studied.
