Creep Buckling — A General View of the Phenomena
A consistent account of the principal phenomena of creep buckling is presented in relation to a series of simple structural models. Materials with both limited and unlimited creep behaviour are included in this general survey. Two important concepts, introduced in earlier papers, are developed further — that of the locus or surface of elastic critical points at which the creeping structure collapses, and that of the long-term elastic critical load below which a structure of limited creep material is prevented from ever reaching a creep collapse condition. Experimental evidence is presented in support of these, but questions are raised as to the usefulness of the critical point locus/surface concept in relation to statically indeterminate structures.
