四周均布剪力作用下含圆孔无限大矩形薄板力学性能的理论研究

Theoretical Study on Mechanical Properties of the Infinite Rectangular Thin Plate with a Circular Hole under the Action of Uniformly Distributed Shear Force

应力集中严重影响开孔构件的承载能力和使用寿命。由此,本文对四周均布剪力作用下含圆孔无限大矩形薄板的力学性能进行理论研究,得到应力的解析解,并基于理论研究结果对孔口应力集中情况进行讨论。

Stress concentration seriously reduces the bearing capacity and service life of the member with holes.In this paper,the mechanical properties of infinite rectangular thin plate with circular holes under uniform shear force were studied theoretically,and the analytical solution of stress was obtained.Based on the theoretical results,the stress concentration at the orifice was discussed.
