*Expressed using the ratio of the yield stress in the biaxial test against that in the uni-axial tensile test. **In each method, the yield stress from the uni-axial tensile test was used to determine the critical value for prediction of yield strength in biaxial tests. A “+” sign means overprediction and a “−” sign means underprediction. |
