Abstract
Numerical analysis have been performed on tensile test experiment data toevaluated the performances of a 9 microns thick aluminium foil. The identification of theanisotropic material properties is based on tensile tests performed in 11 different anglesfrom 0◦to 90◦from the rolling direction. By least square fitting and extrapolation tozero load the elastic modulus is, as opposed to the general belief, proven to be very closeto the expected bulk values for this specific material. The elastic modulus is shown tobe anisotropic with a stiffness variation of aound 15%. Minimum stiffness is obtained inaround 45◦from the rolling direction
