Failures analysis of particle reinforced metal matrix composites by microstructure based models

Automatic generation of 2D micromechanical finite element model of silicon–carbide/aluminum metal matrix composites: Effects of the boundary conditions

“…In order to represent the microstructure of composites, Tursun et al [4], Sozhamannan et al [9] and Zhang et al [16] applied the digital image technique, which requires special software, to generate the mesh data for simulation. Qing and Mishnaevsky [17][18][19], Wang et al [20][21][22] and Peng et al [23] generated the microstructure of composites through random movements of particles from their initial regular arrangement, such as hexagonal and/or square lattice arrangements.…”

“…Ekici et al [8] studied the influence of particle size and volume fraction on the indentation response particle reinforced MMC. Sozhamannan et al [9] studied the macroscopic response and the local stress/strain field of MMCs under tensile loading conditions using scanning electron microscope images. Yuan et al [10] simulated the tensile stress-strain curve through the axisymmetric cell model consisting of interface, matrix and reinforced particle.…”

Deformation rate effect on the microstructure and mechanical properties of Al–SiCp composites consolidated by hot extrusion

“…In addition, the stress field in the matrix is more drastically affected by the concentration of the particles in the cluster region. When applied stress is increased, the strain fields in the cluster region collapse and the ultimate strength starts to decrease [27].…”

A micromechanical fracture analysis to investigate the effect of healing particles on the overall mechanical response of a self‐healing particulate composite

“…They investigated the effects of pore defects and residual stresses on the crack path by employing Griffith energy‐based fracture mechanics approach. An elastoplastic finite element analysis was conducted on an SEM‐based finite element model, and the stress‐strain response was reported as a function of microstructural features such as particle clustering . A comprehensive investigation of the effect of distribution, size, and shape of the particulate reinforcements and interphase properties on the fracture behaviour of a Al 2 O 3 /TiB 2 composite has been conducted.…”

“…Microstructure-based finite element simulations have been conducted in the literature to analyse fracture and damage in particulate composite systems. [17][18][19][20][21][22][23][24][25] For examples, microstructures representing a random distribution of irregularly shaped SiC particles in an aluminum matrix were simulated using two-dimensional linear elastic approach involving stress intensity factor as the crack driving force parameter. 17,18 The effect of particle clustering was quantified, and the resulting crack paths were compared with experiments.…”
