| 摘 要： | 膨胀金属薄膜广泛应用于世界各地的人行道设计和装饰用途。在文献中,很少有关于膨胀金属结构单元特性的信息。本文旨在研究压应力作用下方形和圆管状的膨胀金属薄膜的轴向破坏。当金属开始膨胀时,在金属片中可得到一种类似于钻石的单元,然后这些单元的特点是有两个几何轴线。一系列的试验测试可以印证膨胀金属的主轴和压力载荷之间角度的影响。从结果来看,根据轴线的方向有三种类型的破环模式:1)模式1的特点是塑性破坏机制;2)模式2会在个别元件处产生局部屈曲;3)模式3为管壁的整体屈曲。

Experimental Investigation on the Axial Collapse of Expanded Metal Tubes |

| Abstract: | Expanded metal sheeting is widely used around the world for catwalks,granting,and decorative purposes.In the literature,little information can be found regarding the behavior of structural elements made of expanded metal.This paper is aimed at studying the axial collapse of squared and round tubes made of expanded metal sheeting under compressive loading.When expanding the metal a diamond-like cell pattern is formed in the metal sheets,then these patterns are characterised by two geometrical axes.A set of e... |
