Special Issue Information

Dear Colleagues,

Nanoindentation has been widely utilized for the in situ assessment of material properties. With the rapid development of the fields of micro-nano manufacturing and MEMS, nanoindentation tests combined with related theoretical analyses, multi-scale simulations, and machine learning, etc., will show broad application prospects in the characterization the of mechanical parameters and deformation mechanism of various functional materials. Researchers from the fields of mechanics, materials, and physics, etc., are expected and welcome to contribute to this Special Issue. Related topics of interest include, but are not limited to, the following:

  • Mechanical parameters acquisition from indentation;
  • Indentation scale effect and strain gradient theory;
  • Nanoindentation deformation mechanism and multi-scale simulation;
  • Dynamic indentation test device and characterization methods;
  • Data-driven indentation characterization and analysis;
  • Nanoindentation characterization method dependent on material type.

Nanoindentation-based fracture toughness measurements of three different materials based on copper oxide with a Berkovich indenter are fascinating topics in material science. The main purpose of this study was to calculate the fracture toughness in mode I (KIc) for three copper oxide coatings (Cu+CuO) deposited on a steel substrate by the DC magnetron sputtering method. The parameter KIc can be referred to as the critical load (Pcritical), where the cracking process is initiated uncontrollably. The basic mechanical parameters, such as the hardness and Young’s modulus of Cu+CuO coatings, were determined using a Berkovich nanoindenter operated with the continuous contact stiffness measurement (CSM) option. Structural observation was performed by scanning electron microscopy (Helios). Using the nanohardness tester from Anton Paar with a Berkovich diamond indenter with experimentally selected load allowed generation of visible and measurable cracks, which were necessary for KIc calculation. Crack lengths were measured by scanning electron microscopy (SEM Hitachi TM3000). The obtained results indicated that the values of hardness and Young’s modulus of Cu+CuO coatings decreased as the power of the magnetron source and the fracture toughness coefficient increased. In the case of the presented study, the Laugier model was chosen for KIc determination. Full article
