Strain and strain rate in torsion test
Original language description
Torsion plastometry is one of the most widely recognized methods of laboratory research for exploring deformation characteristics of hot-formed metallic materials. It is one of the two basic tests (together with compression test) which offer the arrangement where one thermomechanical parameter is kept constant while the other two out of three (temperature, strain rate, strain) are varied. A torsion test is based on the effects of shear stress and is the only test to involve large strain magnitudes without effects of external friction. Its drawbacks include the fact that the level of strain between the axis of the sample and its surface is not uniform, which makes the resulting microstructure difficult to define. Evaluation of measured parameters, i.e.the torque, number of twists and duration of the test is based on three principles. It involves finding the mathematical relation for true strain using the strain intensity relationship and obtaining, in turn, the strain rate intensity. T
