| 摘 要： | 本文提供了一种直接显示集中受力半无限平板和对径受压圆盘应力场的几何云纹法。实验表明,用两个完全相同的辐射格栅和两个Wulff格栅重叠错位后就能形成集中受力半无限平板和对径受压圆盘的等差线和等倾线。

| Abstract: | Presents a geometric moire method to directly disply stress fields (isochromatics and isoclinics) of a semi-infinite plate under concentrated load and a diametrically pressed circular disk. Experiment shows that the stress fields or the isochromatics and isoclinics of the plate and the disk can be produced by duplicating and shearing two identical radial grids and two Wulff grids. Appling principle of geometric moire method, derives relative equations of stress fringe of the plate and the disk, and so that proves the method utilizable. The method may be used for other samples which are more complicated than the two as mentioned in the article. |
