- Application of nanoindentation testing to study of the interfacial transition zone in steel fiber reinforced mortar (2009, methodology): “Later, the indentations of rigid indenter into an elastic-plastic half space have been experimentally conducted for different engineering materials [27,43]; and the finite element method has been used to study the material properties during elastic-plastic indentation to establish how the indentatio”
- The effect of crystal orientation on the indentation response of commercially pure titanium: experiments and simulations (2010, methodology): “During indentation one can measure continuous load–displacement, and after indentation the modulus and hardness results can be calculated from the unloading portion of the experiment (Pharr & Bolshakov 2002).”
- A review on the mechanical properties of cement-based materials measured by nanoindentation (2015, background): “From the initial slope of the elastic unloading in the load–depth curve, two mechanical parameters can be obtained [68].”
- Calculating the elastic modulus from nanoindentation and microindentation reload curves (2007, background): “According to Pharr and Bolshakov [6], both the unloading and reloading processes are elastic, and what happens during reloading must be exactly the reverse of what happens during unloading.”
- On the uniqueness of measuring elastoplastic properties from indentation: The indistinguishable mystical materials (2007, background): “The self-similarity of P d curves of sharp indentation on bulk materials makes the conical indenters more widely used in indentation analysis: the resulting loading P d curve is quadratic and the unloading P d curve can be fitted into a power-law relationship (Pharr and Bolshakov, 2002).”
- An analysis of nanoindentation in linearly elastic solids (2008, background): “1) and is given by (Fischer-Cripps, 2004) hc ¼ h 2ðp 2Þ p P dP=dh : ð5Þ Note that the coefficient of the second term on the right-hand side of (5) is often represented by a constant in literature, whose value is dependent on the geometry of the indenter (Pharr and Bolshakov, 2002).”
- Property investigation of individual phases in cementitious composites containing silica fume and fly ash (2015, methodology): “Two mechanical parameters were simultaneously obtained from the initial slope of the load–depth curve [10].”
- Determining the elastic modulus and hardness of an ultra-thin film on a substrate using nanoindentation (2009, background): “that the displacement during the unloading segment of an indentation is elastic even if the material has undergone significant plastic deformation on loading—at least in the absence of time-dependent deformation or a strong Bauschinger effect.(1,8,17) The entire unloading process can be modeled as t”
