A Finite Element Analysis for a Supercritical Particulate Process

Bakhbakhi Y., King Saud University, SA

Nonconventional processing methods can lead to the development of materials with unique chemical, physical or mechanical characteristics that make them suitable for specialized applications. One such method is crystallization with supercritical fluids (SCFs), where the [...]

Multi-Scale Modeling of Polymer Nanocomposites

Adam L., Delaere K., Gérard J.-S., Assaker R., Doghri I., Kaszacs M., eXstream engineering S.A., BE

Due to the small size of nano-inclusions, their surface becomes an important factor determining the composite properties. For “microcomposites” (with inclusions larger than one micron) it is often sufficient to consider the phases’ bulk properties, [...]
