Measurements of effective elastic modulus in wound rolls of thin aluminum foil
Original language description
Elastic properties of wound rolls are used as an input for simulations of stress-strain state in the roll after winding in order to optimize quality of foils. The effective elastic modulus in direction perpendicular to the layers of foil is challenging to measure because it is dependent on interlayer pressure and is generally much smaller than the bulk elastic modulus of the material. Normally, stacks of many layers of foil are pressed in order to determine the interlayer-pressure dependence on effective elastic modulus. In this study, a similar test was carried out using multiple methods including standard compress tests with strains evaluated by using video extensometer as well as digital image correlation of the stack surface and instrumented indentation method. The results given by all methods were compared. Moreover, multiple stack thicknesses were tested in order to evaluate the influence of stack size on the effective modulus. The tested foil was made from aluminum alloy AA8079 and was 13 µm thick.
