Abstract
The presented paper describes the measurement of anelastic effects of electric discharge machined titanium load cells. The load cells were manufactured with a new design, which allows an interferometric measurement of the anelastic effects with a good signal to noise ratio. FEM simulations are used to calculate the arising stresses. An improved data evaluation reduces the influence of drift effects, which allows a better comparison of load cell specimens with different materials and hinge thicknesses. The observed effects, including their sensitivity towards material thickness and load, are compared to the effects of a common aluminum alloy.
