Abstract Scope |
Indentation testing is widely utilized to characterize hardness of materials. This method is performed on different scales of indenting force, indenter size and dimensions of the indented material. The different scales do not always yield the same hardness output or reading due to material length scales. In addition to the scales aforementioned, the shape of reinforcing particles or second phases and their orientation in composites have a pronounced influence on the indentation hardness. In this work, 3D non-linear finite-element analysis, using a purely elastic indenter on Metal Matrix Composites (MMCs), was performed to investigate the effects of particle shape and particle orientation on the ability of the MMCs to resist localized plastic deformation. According to our simulation results, both the particle shape and the orientation of particles affect the hardness readout especially at scales when the size of the indenter is more comparable to the size of particles. |
