Abstract
The paper presents a displacement incrementation procedure to handle m ultiple loadings in post-buckling analysis of structures by Dynamic Re laxation (DR). This procedure is generalized and a 'variable-arc-lengt h' method is proposed to automate the tracing of load-deflection path. The resulting algorithm exactly traces limit points and can handle 's nap-through' or 'snap-back' problems. The efficiency of the proposed m ethod is demonstrated by typical examples of truss, beam and shell str uctures.
