Analysis of nanoindentation of soft materials with an atomic force microscope [PDF]
, 2011 Nanoindentation is a popular experimental technique for characterization of the mechanical properties of soft and biological materials. With its force resolution of tens of pico-Newtons, the atomic force microscope (AFM) is well-suited for performing ...

MicromachinesWhen testing biological samples with atomic force microscopy (AFM) nanoindentation using pyramidal indenters, Sneddon’s equation is commonly used for data processing, approximating the indenter as a perfect cone. While more accurate models treat the AFM tip as a blunted cone or pyramid, these are complex and lack a direct relationship between applied ...

Molecular dynamics of cleavage and flake formation during the interaction of a graphite surface with a rigid nanoasperity [PDF]
, 2009 Computer experiments concerning interactions between a graphite surface and the rigid pyramidal nanoasperity of a friction force microscope tip when it is brought close to and retracted from the graphitic sample are presented.

Material independent crack arrest statistics
, 2004 The propagation of (planar) cracks in a heterogeneous brittle material characterized by a random field of toughness is considered, taking into account explicitly the effect of the crack front roughness on the local stress intensity factor.
