Abstract: In this study, the effects of particle volume fraction, particle size and particle distribution is investigated on the indentation behavior of metal matrix composites (MMCs) using extended finite element approach. The particles are assumed to be circular in shape. The matrix (Zr2.5Nb) is assumed to have an elasto-plastic behaviour whereas the particles (SiC) are assumed to have linear elastic behavior. The indentation response of the MMCs is investigated using random particles distribution for different reinforcement volume fractions (10 to 30%). Plastic behavior of matrix is described by the von-Mises yield criterion with Hollomon's power law equation. The large deformation under the indenter is modelled by updated Lagrangian approach. A penalty approach is employed to impose the contact constraints at the interface between the indenter and matrix. An efficient node-to-segment (NTS) frictionless contact algorithm is employed to model the contact behavior. The effect of particle size, distribution and volume fraction on the residual von-Mises stress and equivalent plastic strain is also investigated. © 2017 The Authors.
