Experimental And Numerical Study On Axial Compression Of Metal Tubes With Holes

Abstract
The main objective of this research is to investigate the effects of presence of holes in circular metal tubes on the deformation modes and load-displacement diagrams, during axial compressive loading, experimentally and numerically. For this purpose, some intact and perforated tubes with two, three and four holes in their mid-height were prepared and were subjected to the axial load between two rigid plates in quasi-static condition. The deformation modes of tested tubes is described and their load-displacement diagrams are sketched. Also, all of the experimental results compared with the numerical results. The numerical simulations are performed by ABAQUS finite element package. Good agreements are observed between experimental results and finite element simulations.
