On the experimental device of metallic membrane bulging, the measuring of in-plane true strain, transverse plastic strain at the pole of sheet, and the contour shape of sheet can be done. So that the relationship between true stress and true strain in the all deformation range of metallic sheets can thus be built up. Furthermore, the changing pattern of elasto-plastic and plastic Poisson's ratio can also be obtained.

在平膜鼓胀装置上，通过测量膜片极顶的面内真应变和横向塑性应变以及膜片的轮廓形状，并计人泊松比随变形过程发生的变化，可建立二向应力状态下箔材从弹性经塑性至破裂的整个变形范围内真应力和真应变的关系，同时还可以得到弹塑性泊松比和塑性泊松比的变化规律。
