COUPLEFLO is a two-dimensional finite-element code for plane strain or axisymmetric analyses of thermomechanically coupled systems. It is capable of analyzing the creep flow on non-Newtonian fluids or the secondary creep of solids. COUPLEFLO solves equations for conductive--convective heat transfer to determine the thermal response of a system. Thermomechanical coupling between the flow field and temperature distribution can exist in terms of temperature-dependent materials properties, temperature-dependent body forces, viscous dissipation, material convection, and changing system geometry. Either transient or steady-state problems can be analyzed in Eulerian or quasi-Lagrangian reference frames. Part I: Theoretical Background contains the governing equations, finite-element formulation, and verification of the code capabilities. Part II: User's Manual contains instructions for code use. 12 figures.
