Since the manufacturers and users of sheet metal parts are aiming at reducing the weight of the component, some components are made out of perforated sheet metals. As the use of perforated sheet metals is wide, its behavioural study is important. An attempt is made here to study its structural behaviour. Finite element analysis is used to analyze the deformation behaviour of perforated sheet metals. After the modelling of perforated sheet metal plate having square and hexagonal perforation, uniaxial tensile load is applied. The FEA is carried out using commercial FE software ANSYS to find its structural behaviour with respect to relative density and the results obtained are compared with literature. Sheet metals with hexagonal perforations are found to have better load bearing capacity and higher stiffness for particular relative density and hence they are better than square perforations at higher factor of safety.
