| Abstract: | Some theoretical dervation had been made on the calculation of stress and strain of a cross-shaped experimental plate.An approximate calculating formula was put forward.Checked against the resuls of the strain gage method and the graphs of FEM,the formula was proved to be correct. |

| Keywords: | biaxial stress principal stress straingage method iso-stress curves. |
