Details of the deformation processes are examined using 2-dimensional and 3-dimensional FE models. Typical histories of deformation of single and parallel steel tubes and their load-compression curves are. presented. Good agreement is reported between the FE force histories of tubes with those obtained experimentally. Using the 3-D model, O/t of 82, the tube deformation transforms from concertina mode to diamond mode, whereas the 2-D model deforms in a concertina mode for all values of Olt ratio. For parallel tubes, it is shown that load-carrying capacity is apparently not equal to the. sum of the load-carrying capacities of each tube acting alone  ISSN : 1319-0989  Journal Name : Arts and Humanities Journal  Volume : 14  Issue Number : 2  Publishing Year : 1423 AH 2002 AD  Article Type : Article  Added Date : Thursday, December 31, 2009  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email عبدالغفار أزهري الجاوي ALJAWI, ِAbdulghafar Azhari Researcher Doctorate a_aljawi@hotmail.com Files File Name Type Description  24583.pdf pdf Numerical Simulation of Axial Crushing of Circular Tubes Back To Researches Page
