Notes:
Micro-indentation has been widely used to evaluate the mechanical properties ofmaterials. It has also been considered to be an important measure in the study of machinability ofdifficult-to-machine materials such as metal matrix composites (MMCs). Because of the complexityof deformation of an MMC and the interaction in the vicinity of contact zone between the indenterand work material, an analytical or experimental method is unable to predict the detaileddeformation process. The present paper uses the finite element method to investigate the behaviorof MMCs subjected to micro-indentation by a spherical indenter including the development ofstress and strain fields in the MMCs during loading/unloading. Particle fracture, debonding anddisplacement, and inhomogeneous deformation of matrix material were explored and comparedwith the experimental results reported in the literature. The analysis also provides an insight forunderstanding the formation of residual stresses in machined MMC components
