Computer simulations of “realistic” partially anisotropic microstructures statistically similar to real microstructures

Insights into local shockwave behavior and thermodynamics in granular materials from tomography-initialized mesoscale simulations

“…In contrast to the microscopy methods employed by Eakins and Thadhani 15 and Singh et al, 19,20 X-ray tomography does not require granular samples to be cast in a polymer and sectioned prior to study. A notable use of X-ray tomography to provide realistic mesoscale shock simulation geometries is a detailed investigation of heterogeneity in aluminumpolyvinylidene fluoride (Al-PVDF) foams.…”

An X‐FEM and level set computational approach for image‐based modelling: Application to homogenization

“…Some authors made the choice to analyze so‐called realistic microstructures, which are generated using statistical data extracted from the images, see 8–12 among others. In these papers it is underlined that classical unit cell models, idealized microstructures or any simplifying assumption about morphological characteristics affect the local stresses prediction.…”

“…In these papers it is underlined that classical unit cell models, idealized microstructures or any simplifying assumption about morphological characteristics affect the local stresses prediction. Therefore, it is mandatory to build microstructures that are statistically equivalent to the real ones, comparing for example their two‐point correlation functions 8, 9.…”
