The design and manufacture of composite materials have evolved into a new era with nanotechnologies, 3D printing, advanced powder technologies, computer aided design, and high performance computation. Sixty to eighty percent of manufactured products are manufactured via particle-based processes and this industry has exceeded a combined market value of one trillion dollars per year in the U.S. alone. Driven by the broad industrial applications including energy, infrastructure, defense, and composite materials engineering, the mixing of powders and granular materials and evaluation of the effective properties have been a very demanding research area. In those applications, it is generally required that the ingredients be mixed uniformly maintaining a certain concentration to meet quality and performance goals. While considerable progress in understanding the dynamics of dry granular materials has been made recent years, the physical mechanisms underlying the properties of wet systems or in viscous fluids remain largely obscure. In addition, during the manufacturing phase and service life of the material systems, particle’s motion and interaction may significantly depend on the environmental factors, including magnetic, electric, and mechanical excitements. In addition, understanding the evolution of material behavior with the particle distribution is always crucial to the design and manufacture of those materials.
This minisymposium will provide a platform to exchange the research results on computational modeling and simulation of the mechanics of many particle systems under multiphysical and mechanical excitation and to share emerging applications of the corresponding materials, research methodology, and software packages. Interested topics are sought (but not limited to) in one or more of the following:
1. Continuum or discrete methods for particle simulations
2. Multiphysical interactions between particles
3. Virtual experiments of particle mixing/blending
4. Multiphase particulate flow and sedimentation
5. Bubble formation and collapse toward foamed composites
6. Particulate composites subjected to mechanical excitation
7. Damage and failure analysis of particulate composites
8. Other related subjects
