摘要：

Square tubes of aluminium and mild steel, placed on a rigid flat surface, were compressed by wedge-shaped and flat-faced indenters of short width in an Instron machine. Their collapse behaviour under different indenters was studied and typical histories of their deformation and load-compression response are discussed. A simplified analysis, which considers the formation of stationary and travelling hinges and employs certain assumptions based on the experimental results, is presented for the description of the collapse behaviour of the tubes. The results obtained thereby have been compared with the experimental results. © 1990.
