... the striking force and the reduction in vibration amplitude during striking. The second one is between the striking force and the permanent indentation depth created by the strike. These linear force relationships offer the opportunity to realize real-time monitoring and force-based feedback control of PVST...

... as a fundamental problem as follows: We want to predict y from x , where x is a set of controlled inputs comprising those listed in Table 2 , and y is a set of interested outputs, comprising both the indentation depth and the cross-sectional area. This problem might be approached by constructing a mapping...

... in the substrate material as well as the indentation profile on the substrate surface. The model prediction of indentation profiles is compared with the experimental data. The residual stresses in the depth direction are also validated against the X-ray diffraction measurement data for 4140 steel and Ti–6Al–4V...

... deformation (DPZD) model developed in Part I ( Shi et al., 2010, ASME J. Manuf. Sci. Eng., 132, p. 051008. ) of this study with quasi-static indentation (QSI) tests, orthogonal cutting tests at room temperature (RT) and high temperature. The QSI tests are used to capture the material properties in the quasi...

...Fabrizio Quadrini; Erica Anna Squeo In this study, the density of powder metallurgy compacts was measured by means of small indentation. Zinc (Zn) and aluminum (Al) tablets were fabricated by cold compaction of powders: different tablet densities were obtained by changing the packing pressure...

... Editor: T. R. Kurfess. All the nanoindentation tests were performed using the Hysitron Triboindenter with a diamond Berkovich indenter. The total included angle on this tip is 142.3 ° , with a semi-angle of 65.35 ° . Before calibrating the indenter, a machine compliance...

... are extended to facilitate the prediction of dynamic cutting forces. Separate thrust, torque, and radial force models for the major cutting edges, secondary cutting edge, and for the indentation zone are formulated. The effects of drill installation errors on the radial cutting forces acting on the chisel edge...

.... Critical depth, at which ductile-to-brittle transition in deformation occurs, was assessed for the hard brittle materials. Limits of ductile mode indentation for hard brittle materials were discussed in detail. Variation in the depth of structures in an imprinted mark was studied. Timp, G., 1999, Nano...

... residual stresses in resistance spot-welded low carbon steel structures using a specially designed indentation device. The effect of the indentation process parameters on the mechanical properties of the resistance spot weld was investigated. Comparisons of the mechanical properties and qualitative results...

...S. P. Moylan; S. Kompella; S. Chandrasekar; T. N. Farris Nano-indentation has become an important tool in the study of mechanical properties of solids at small length scales, ever since its formulation as a technique in the early 1980s. The small size of an indentation, typically one micrometer...
