Influence of Material Compressibility on Displacement Solution for Structural Steel Plate Applications

Abstract EN

Displacement field calculations are necessary for many structural steel engineering problems such as cold expansion of holes, embedment of bolts and rivets, and installation and maintenance of external devices.

To this end, rigorous closed form analytical displacement solution is obtained for structural steel open-hole plates with in-plane loading.

The material of the model is considered to be elastic perfectly plastic obeying the von Mises yield criterion with its associated flow rule.

On the basis of this solution, two simplified engineering formulae are proposed and carefully discussed for practical engineering purposes.

Graphical representations of results show validity of each formula as compared with rigorous solution and other studies.
