Peridynamic Investigation of Stress-Strain Response and Fracture Behavior Variations in Micro-CT Images of Mock Energetic Nanocomposites
… effective stiffnesses were compared to the Mori-Tanaka approach for effective material property estimation, and the results were broadly consistent with the Mori-Tanaka solution. Damage-enabled cases were also conducted, and the results from the y-direction cases revealed unique …

A Micromechanics Study on Ferroelectrics and Multiferroic Composites
… for the two-phase ferroelectric composites, the Mori-Tanaka Method can be applied to analyze and solve the overall effective electro-mechanical coupling behavior of the system. We demonstrate how the overall nonlinear effective physical properties depend on the phase volume concentration and …

Microporoelastic modeling of organic-rich shales
… namely a matrix-inclusion morphology (Mori-Tanaka) for immature systems and a polycrystal/ granular morphology for mature systems. Also, we show that interfaces play a role on the effective elasticity of mature organic-rich shales. The models are calibrated by means of ultrasonic pulse …
