 note = {The present paper deals with the simulations of impact torsion and the errors of the measured values are also discussed. A strain rate dependent theory was used for the stress analysis of a short thin cylindrical specimen of SS41. Two impact torsional tests were simulated. One was at high strain rates of the order of 10²/sec or more by the Hopkinson pressure bar method. The other was at low strain rates of the order of 10/sec or less by the usual high speed rotation. In these cases the errors were estimated by comparison of the stress measured and that corresponding to the strain - strain rate relation measured. As a result, it was found that the error decreased as the rise time of the input wave increased at high strain rates, but that it did not so change as the length of the specimen changed. The measured stresses at all conditions adopted had good accuracy within 1% error, after the stress wave traveled back and forth about 4 times in the specimen. At low strain rates, the accuracy of the measured stresses became good as the rise time of the input wave increased and the length of the load cell decreased.},
