Abstract: PURPOSE: An evaluation method of the anisotropic residual stress using the instrumented indentation technique is provided to measure isotropic residual stress among the mechanical property valuations of a material by an anisotropic indenter. CONSTITUTION: An instrumented indentation test using an anisotropic indenter proceeds after applying biaxial tension residual stress including one axial tension and isotropic property. It is compared that a slope of the indentation load-depth curve in indentation and the slope of the indentation load-depth curve under non-stress while the biggest residual stress is being applied in a longitudinal axis of the anisotropic indenter. It is compared that the slope of the indentation load-depth curve in indentation and the slope of the indentation load-depth curve under non-stress while the longitudinal axis of the anisotropic indenter is in parallel with the direction where the biggest residual stress is applied.
