Elastic modulus of claystone evaluated by nano-/micro-indentation tests and meso-compression tests
Toarcian claystone such as that of the Callovo-Oxfordian is a qualified multiphase material. The claystone samples tested in this study are composed of four main mineral phases: silicates (clay minerals, quartz, feldspars, micas) (≈86%), sulphides ...

Assessment and validation of SPH modeling for nano-indentation [PDF]
Nano-indentation tests are important techniques in material science. Over the past two decades, many numerical approaches have been proposed to model and simulate the nano-indentation process. In this paper, the possibility of modeling the process using a meshless numerical technique, known as smooth particle hydrodynamics (SPH), is explored.

Effect of loading strain rate on nano-indentation response of an aerospace grade epoxy polymer
Depth sensing indentation holds the promise of local mechanical properties determination. However, the number of studies on materials that exhibit time-dependent and hydrostatic pressure-dependent behavior is still scarce.
