The Yoshida buckling test (YBT) is a commonly used method to evaluate the wrinkling behavior of sheet metals; however, it is difficult to reflect the actual in-plane stresses in many sheet forming processes owing to the limited variation in the stress state. Furthermore, the test is impracticable for some low-ductility materials because fracture typically occurs before wrinkling. This paper proposes an approach for examining the wrinkling properties of sheet metals using uniaxial tension of plates with a central cut-out; a relevant wrinkling model is established using stress analysis of a finite perforated plate and an energy method. The results show that the typical stress distribution modes around the central hole before wrinkling are biaxial compression in the top/bottom domains and biaxial tension in the lateral domains, and the mode changes with the hole size and tensile displacement. The ratio of transverse to axial stresses increases with the diameter/width ratio; this leads to a larger influence of transverse nonuniform compressive stress, consequently decreasing the critical wrinkling stress. The wrinkling tendency in perforated sheets is more sensitive than that in a conventional YBT specimen; thus, it can be used to capture the subtle distortion of wrinkling for low-ductility materials. A second wrinkling phenomenon that occurred in plates with large holes under a large tensile displacement was observed and addressed.

吉田屈曲试验（YBT）是一种常用的方法来评估钣金的起皱行为；然而，由于应力状态的变化有限，在许多板材成形过程中很难反映实际的面内应力。此外，该测试对于一些低延展性材料是不切实际的，因为断裂通常发生在起皱之前。本文提出了一种使用具有中心切口的板的单轴张力来检查金属板起皱性能的方法；利用有限穿孔板的应力分析和能量法建立了相关的起皱模型。结果表明，起皱前中心孔周围典型的应力分布模式为顶部/底部区域的双轴压缩和横向区域的双轴拉伸，模态随孔径和拉伸位移而变化。横向应力与轴向应力的比值随着直径/宽度比的增加而增加；这导致横向非均匀压缩应力的更大影响，从而降低临界起皱应力。穿孔板的起皱倾向比传统的YBT试样更敏感；因此，它可用于捕捉低延展性材料起皱的细微变形。观察并解决了在大拉伸位移下具有大孔的板中发生的第二种起皱现象。从而降低临界起皱应力。穿孔板的起皱倾向比传统的YBT试样更敏感；因此，它可用于捕捉低延展性材料起皱的细微变形。观察并解决了在大拉伸位移下具有大孔的板中发生的第二种起皱现象。从而降低临界起皱应力。穿孔板的起皱倾向比传统的YBT试样更敏感；因此，它可用于捕捉低延展性材料起皱的细微变形。观察并解决了在大拉伸位移下具有大孔的板中发生的第二种起皱现象。
