Numerical Analysis of Post-Buckling Behavior of Elastic Plastic Arches

  • Conference paper
Computational Mechanics ’86

Summary

The post-buckling behavior of inelastic arches is analyzed numerically using a discrete model that is composed of finite rigid bars connected with history-dependent nonlinear springs. A special attention is paid for elucidating the effect of the reversed plasticity on the load-deflection curve during and after the snap-through. Numerical calculation is carried out for the symmetric in-plane deformation of shallow circular arches which are subjected to a concentrated vertical load at the apex. The conventional analysis neglecting the reversed plasticity is found to underestimate significantly the deflection during and after the snap-through.
