Reliable knowledge about flexural strength of sheet metals is very important for sheet metal bending process. Young's modulus and cross sectional area determine the flexural strength of sheet metals. For perforated sheet metals, the presence of holes reduces the cross sectional area and hence the flexural strength is affected. In this paper, an attempt is made to study the influence of presence of holes on flexural strength of Aluminium 8090 alloy sheets. Experiments are conducted to study the influence of hole size, percentage of open area and hole arrangement pattern. © 2006-2013 Asian Research Publishing Network (ARPN).
