abstract

Continuous indentation technique has been widely studied because of its various merits, such as simple experiments, short experiment time and nondestructive technique. It is proved that the technique can produce tensile properties from the load-depth curves without optical observation by many researches. When the experiment is performed, it is, however, very difficult to determine the values of various experimental parameters that affect derived tensile properties by inserted in numerical analysis procedure. In this study, the effects of the parameters were studied using Taguchi method which is a kind of design of experiment (DOE). The ratio of indentation depth to indenter radius, the indenter radius, the number of unloads and the unloading ratio were selected as the main parameters. The changes of derived tensile properties by the main parameters were analyzed by calculating signal-to-noise (SN) ratio. Finally, the optimum values of each parameter were determined. The tensile properties evaluated with the optimum values showed much better agreement to those from uniaxial tensile test.
