“…[16][17][18][19][20][21][22][23][24][25] Especially, various analytical models, such as the shear-lag model and cylinder model, were introduced to analyze the elastic mechanical properties of misaligned or randomly distributed fiber-reinforced polymer matrix composites. [22][23][24][25] However, in the case of MMC, it is necessary to consider the plastic deformation of matrix to explain the deformation behavior of composite. Also, the stress distribution obtained from the finite element analysis is too complex to estimate the effect of discontinuous reinforcements on plastic deformation of MMCs.…”

The load-transfer efficiency of reinforcement, in cylindrical forms in metal-matrix composite (MMC), was analyzed based on the shear-lag model. Both the geometric shape and alignment of reinforcement were considered. The stress transferred to a misaligned whisker was calculated from differential equations based on the force equilibrium in longitudinal and transverse directions. A new parameter, defined as effective aspect ratio, was used to indicate the load-transfer efficiency of misaligned reinforcement. The effective aspect ratio was formulated as a function of aspect ratio and misorientation angle of reinforcement in MMC. A probability density function of misorientation distribution was used to estimate the strengthening effect of all misaligned whiskers distributed in the matrix. Considering the contributions of both effective aspect ratio and misorientation distribution on load-transfer efficiency, a generalized shear-lag model was proposed to explain the mechanical anisotropy of discontinuous reinforced MMC.

“…According to the Orowan theory, strength of an alloy or composite material is inversely proportional to inter-particle distance. It is well known that the interfaces between particles and solder matrix act as obstacles for dislocation motion [26][27][28]. Therefore, this increasing particle distance decreased interface area and may lead to the reduction of the dislocation motion resistance as well as the dislocation sources.…”

“…The distribution irregularity (i.e., directionality that is influenced by the direction of stress applied during manufacturing) gives unique mechanical behavior and anisotropy to particulate composites. [9][10][11] Ganesh and Chawla [9] experimentally investigated the effect of SiC particle orientation on the tensile and fatigue properties of SiC particle-reinforced Al composites processed using high-temperature extrusion.…”

“…[8] Indeed, these qualities, along with the direction of applied force, control a number of mechanical properties ranging from short-term strength and hardness to long-term fatigue and creep limits. [9,10] SiC particles usually exist in plate-like shapes with flat edges, and are irregularly distributed in many cases. The distribution irregularity (i.e., directionality that is influenced by the direction of stress applied during manufacturing) gives unique mechanical behavior and anisotropy to particulate composites.…”

In this study, a serial sectioning technique was employed in order to visualize the threedimensional (3D) structure, and to accurately simulate the mechanical and thermal behaviors of SiC particle-reinforced Al composites. Sequential, two-dimensional (2D) optical images of the microstructure were acquired after polishing, and then reconstructed to develop 3D geometries for microstructural analyses and finite element modeling. Experimental compressive and thermal expansion tests were performed for comparison with the finite element method results. The Young's modulus and thermal expansion coefficient of the composite, predicted using the 3D microstructure-based finite element analyses, were in good agreement with the experimental results. Furthermore, the 3D microstructure-based finite element model showed anisotropic thermal expansion behavior that was previously disregarded in the other models used in this study. Therefore, it was confirmed that the combined approach of serial sectioning and finite element modeling provides a significant improvement over 2D and 3D unit-cell modeling.
