Experimental and Numerical Analysis of the Critical Buckling Load of Cracked Sheets

Abstract

Collapse by buckling a quite common phenomenon in sheets under pressure. When these structures caused by defects such as corrosion and cracks the time of the occurrence of this phenomenon is sensitive and critical load to be significantly reduced. Therefore, in this article sheet of aluminum Al 1200 by cracks in a part of the sheet will be considered. Left angle on the critical buckling load effect both experimentally and theoretically calculated. STM-250 experiments using theoretical analysis using Abaqus software is done and the results are compared with theoretical and experimental.
