Abstract The available stress distribution states in conventional Yoshida buckling test (YBT) for testing the sheet buckling properties are limited, thus it is difficult to evaluate the wrinkle-resistant performance of sheet metals under complex forming conditions. In this paper, a method for examining the wrinkling property of sheet metal, using uniaxial tensile tests of YBT samples with circular inner hole in the geometric center, was proposed. The force and deformation characteristics of specimens with various holes during uniaxial tensile tests were qualitatively analyzed, using finite element simulation and physical experiments, the influences of holes on the in-plane transverse stress distribution form and wrinkling behavior were addressed. It was found that circular hole changes the in-plane stress distribution of YBT samples, the compressive stress lies on the both axial sides of the hole while the tensile stress on both transverse sides. The ratio of transverse and axial stress increases with the hole diameter, and the stress state of the maximum compressive stress position changes from transverse compression and axial tension into bidirectional compression. Secondary wrinkling behavior appears in side areas when the hole diameter is large.

Key words： Yoshida buckling test wrinkling circular hole complex forming conditions stress state
