Title: On the quasi-static piercing of square metal tubes
Author(s): Lu, Guoxing; Wang, Xi
Abstract: This paper investigates the energy absorption properties of square tubes pierced by pointed punches under quasi-static conditions. In a series of tests, square section pyramidal punches and conically headed cylindrical punches were pierced slowly into square steel tubes having 40x40mm2 outside dimensions. Wall thicknesses of 1.6 and 2.5mm were tested, and the length of tubes was varied. Some typical loads were plotted against deflection, and a number of interesting conclusions were drawn from the tests. Based on the test results and observations, preliminary theoretical considerations are presented. The theoretical results agree fairly with the experiments.
