| Abstract |
The continuous indentation test, which measures indentation depth with applied load, has been used to evaluate the tensile properties whose accuracy can vary depending on such experimental conditions as maximum depth ratio, indenter radius, number of unloadings and unloading ratio. In this study, Taguchi method, one of the designs of experiment, was applied to quantify the effects of the experimental conditions effectively. Using a signal-to-noise ratio calculated from the error in the indentation tensile properties, the optimum values of the experimental conditions were presented. The indentation tensile properties from the load-depth curves with the optimum conditions showed better accuracy than those with existing conditions. |
