Conventional strain gauge can measure about 15~20% elongation. However, when the steel are ruptured, the strain at the necking region can be much higher than the measurement capacity of the conventional strain gauge. To measure the maximum strain at the necking region a new measurement technique should be developed. In this study, for this purpose image processing method for measuring 2-D strain distribution of tensile specimen of steel is proposed.
