摘要: ) deform by elastic defor-mation, buckling and plastic collapse of their cell wall. At more elevated temperatures, creep con-tributes to the deformation, which becomes time dependant. Deformation creep-bending cellwalls has been analysed in some detail, but deformation creep-buckling not. In this paper we ana-lyse for first cellular structures creep-buckling, deriving critical load andtime required event commence. 7 2000 Acta Metallurgica Inc. Published ElsevierScience Ltd.
