| Abstract: | The diagonal tensile test of thin square plate (YBT-Yoshida Buckling Test)is used to simulate the buckling or wrinkling phenomena of sheets Subjected to non-uniform stretching in forming process of large panels. The buckling process is measured and analysed. On the basis of experiments the effects of material properties ,thickness of sheets , Orientation of specimen and loading condition on the buckling -resistance of sheets are discussed. |
