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
Abstract (Swedish)
Numerical analysis have been performed on tensile test experiment data to evaluated the performances of a 9 microns thick aluminium foil. The identification of the anisotropic material properties is based on tensile tests performed in 11 di↵erent angles from 0 to 90 from the rolling direction. By least square fitting and extrapolation to zero load the elastic modulus is, as opposed to the general belief, proven to be very close to the expected bulk values for this specific material. The elastic modulus is shown to be anisotropic with a sti↵ness variation of aound 15%. Minimum stiffness is obtained in around 45 from the rolling direction.
