Abstract
AbstractThe paper presents the inelastic post‐buckling analysis of truss structures by the Dynamic Relaxation (DR) method. A simplified inelastic finite element formulation for truss element and new algorithms are proposed for Elastic Post‐Buckling (EPB) analysis and Inelastic Post‐Buckling (IEPB) analysis using the DR method. The post‐buckling paths for elastic, EPB and IEPB analyses are completely traced using the variable‐arc‐length method. Four numerical examples are presented to illustrate the application of the proposed algorithms.
