摘要： The present invention relates to a two dimensional stress relaxation testing device in which a plus shaped sample is stretched in mutually perpendicular directions simultaneously to monitor the stress and also the relaxation process of any sheet material in both axes. In view of this advantage, the present device provides the closest approximation to the in situ failure of the material.
