G. Ramesh et Cs. Krishnamoorthy, INELASTIC POSTBUCKLING ANALYSIS OF TRUSS STRUCTURES BY DYNAMIC RELAXATION METHOD, International journal for numerical methods in engineering, 37(21), 1994, pp. 3633-3657
The paper presents the inelastic post-buckling analysis of truss struc
tures by the Dynamic Relaxation (DR) method. A simplified inelastic fi
nite element formulation for truss element and new algorithms are prop
osed for Elastic Post-Buckling (EPB) analysis and Inelastic Post-Buckl
ing (IEPB) analysis using the DR method. The post-buckling paths for e
lastic, EPB and IEPB analyses are completely traced using the variable
-arc-length method. Four numerical examples are presented to illustrat
e the application of the proposed algorithms.
