 note = {The method for predicting the flow curves or the effective stress-effective strain relations, in which the equation of work-hardening coefficient is used, was proposed previously. The method has been applied to analysis some plastic forming processes of metals and alloys, such as hot extrusion and hot rolling. 
The method has been confirmed to be very useful for evaluating the deformation resistance of materials under the realistic deformation conditions, varying strain-rate and temperature in the deformation process, encountered in the practical forming processes.
The equation of work-hardening coefficient involves two experimental constants (rate sensitivity γ_0 and stress sensitivity q) which should be determined analytically from the experimental uniaxial stress-strain curves. The procedure for determining the above constants is strenuous. So it has been desired to have a computer program for the procedure.
One of the computer routine is developed and proposed here. The input data required are the stress-strain curves observed by some isothermal testings performed at some strain rates under basic temperature (room temperature) and some warm and hot working temperatures. Then, the constants are determined as functions of temperature.
The whole program is verified by comparing the flow curves calculated, in which the computer determinants, γ_0 and q, are used, with the experimental ones.},
