Abstract

Bulge Testing is a method used to evaluate the mechanical properties, in particular the elastic modulus and residual stress of a thin film. Air pressure is applied to the membrane and the resulting deflection measured with a plunger type dial indicator. This paper work involves in evaluation of mechanical material properties like stress, strain, young's modulus and poison's ratio including conduction of various tests with Brass, Rubber and Aluminum sheets which are made in the form of thin films and test those films for determining modulus of rigidity and poison's ratio.
