Micromechanical modeling of particulate composites for damping of acoustic waves

Article Abstract:

The self-consistent micromechanical model of a compositeis modified using dilute strain concentration tensor formulation (DCST) in order to allow for the approximation of the effective properties of composites with many disparate coated inclusion properties, geometries and orientation distributions. Several case studies are presented to show the improved modeling flexibility of the DSCT that is therefore an ideal candidate for material-by-design studies for damping applications.

Micromechanical modeling of the static loading of an Al 359-SiC MMC

Article Abstract:

The study concerning the static tensile loading of a particulate reinforced Al 359+20% SiC metal matrix composite material (MMC) is presented. The overall objective of this study is to apply a micromechanical unit cell modeling approach to investigate microstructural deformation in the MMC and to predict its overall tensile stress-strain behavior.
