“…residual stresses, and creep properties. The indentation test is classified as a non-destructive [2] or quasi-nondestructive [3] localized test that can be used for nonstandard specimens. Indentation test is a simple test but extracting the aforementioned properties from a specimen is far from easy.…”

The uncertainties of modern, adaptable sheet metal forming systems are classified into model errors and disturbances. To improve the control of production, disturbances in the forming process need to be reduced. For this purpose, a new data flow system was introduced. It connected the data flow of all influencing material parameters into the “material property control function”. To control on-line the forming production line and acquire necessary material data, an indentation test was implemented. The main parameters to follow in this test are pile-up or sink-in values after the embossing of the ball-shaped tool into the material where the innovative approach of fully anisotropic material description was used. To set-up an optimal indentation test, parametric studies were performed with material data of AW 5754-H22. Finite element simulations were used to evaluate the influences of indenter diameter, contact friction and forming history of used the material. Fully anisotropic material behaviour was considered. Novel to this approach were a) the linking of the linear correlation of pile-up with the indentation depth described by gradient k, and b) the linking of gradient k with different pre-strains by a new power function.

“…Finally, indentation experiments are conducted on Si(1 0 0) and Ge(1 0 0) and the K c values obtained by our suggested method are compared with literature values. To obtain the material properties of Si(1 0 0) and Ge(1 0 0), a recently established spherical indentation-based material property evaluation method by Kim et al [18] is applied.…”

“…The elastoplastic characterization of metals by nanoindentation test remains one of the biggest challenges in the micro-characterization domain [8,9,10] . The methods of elastoplastic characterization by nanoindentation test can provide access to the mechanical behavior [11] at multiple scales and in conditions where the conventional methods of mechanical characterization (e.g.…”

The parameters describing the elastoplastic behavior of the 316 L austenitic stainless steel are identified through inverse analysis based on finite element modeling of the Berkovich nanoindentation test. The true geometry of the Berkovich indenter is introduced in axisymmetric and 3D finite element models using experimental nanoindentation data obtained by adapting the calibration method proposed by Oliver and Pharr [1] . Then, using these true indenter shape models, the elastoplastic parameters of the 316 L are estimated with high accuracy compared to the parameters obtained from tensile test identification. The indentation curve was correctly described by the numerical model for all the analyzed indentation depths, even for indentations inferior to 100 nm, which is a challenge until today. The 3D indenter model produces a residual imprint very close to the experimental indentation mark. The friction analysis between the indenter and the sample surface reveals small changes in the surface deformation, introducing an increase on the hardness, which disappears as the indentation depth decreases.These studies demonstrate that the most important aspect in the elastoplastic parameter identification is the correct representation of the indenter geometry in the finite element model.
