ANALYSIS OF CONTACT OF A RIGID SPHERE AGAINST A DEFORMABLE FLAT
Acta Metallurgica Slovaca, 2015 In the paper the strain hardening effect on the contact of a rigid ball and elastic-plastic flat is considered using experiments and finite element method. The experiments were carried out for DC04 steel sheet metal.

Revealing new depths of information with indentation mapping of microstructures
MRS BulletinAbstract Nanoindentation is crucial in materials science for assessing mechanical properties in submicrometer volumes, and high-speed nanoindentation mapping has evolved it from a localized measurement technique into a scanning-probe-like approach for microstructures, delivering large-area, high-resolution mechanical property maps with more ...

Elastic modulus of claystone evaluated by nano-/micro-indentation tests and meso-compression tests
Journal of Rock Mechanics and Geotechnical Engineering, 2017 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 ...

Effect of temperature and strain rate on indentation size effect at shallow indentation depths
Materials & DesignThis study investigates the indentation size effect in a bcc silicon iron single-crystal tested at different temperatures and strain rates. The classical Nix-Gao model based on strain gradient plasticity and geometrically necessary dislocations starts to deviate from experimental data at small depths due to dislocation interactions not accounted for ...
