Prediction of Stress-Strain Relation of Ti Metal by Indentation Method
壓痕試驗預測鈦金屬之應力與應變關係
並列摘要
In this study the elastic-plastic characterization of a commercially available Ti metal was estimated and compared to that of tensile testing. The measurements are correlated using a model based on reverse analysis algorithms, which enable the extraction of elastic-plastic properties from a given set of indentation data. The results showed that the stress-strain behavior of Ti obtained using large deformation theory exhibited both the material's coefficient of plastic strength (R = 0.831) and work hardening exponent (n = 0.145) greater than those determined by tensile testing. Indentation should be investigated as an alternate mechanical characterization method for small volume like thin films.
