Stress - strain curves description of steels
Original language description
The need for thorough mathematical description of the flow stress curve is increasing, related particularly to its dependence on strain, strain rate, and temperature. This paper explores the potential of an approximate description of the stress-strain relationship. Listed are the principles and the proposed form of simple non-linear (relying on no more than two exponential functions), non-continuous (including the initial linear portion according to the Hooke's law) and approximate models of the dependence of flow stress (stress) on the amount of strain. This model should be applied to specific measured data from stress-strain curves for three strain rates at the temperature range from 1023 to 1273 K. The specimens were made of 9Cr steel. The curves were obtained by processing flat specimens of 10 15 20 mm in the Gleeble compression simulator. Finally, the calculated values were compared with experimentally measured data
