Four Monologues on Sintering

10:00 AM-12:00 PM
Room: Independence B

Sintering is one of the most important industrial processes nowadays, with applications ranging from MEMS and microelectronics to space and automotive industries. Nevertheless, it is, arguably, one of the least understood industrial processes. The reason for this is that sintering is a result of complex physical, chemical and mechanical phenomena working at different length scales which traditionally were modeled separately. In this minisymposium, the speakers will present a discussion of several modeling efforts -- atomistic (molecular dynamics), mesoscopic (Monte-Carlo simulation of grain growth, pore migration and annihilation) and continuum (plastic and nonlinear-viscous models) - with emphasis on establishing connections between the length scales.
