Accelerating phase-field-based simulation via machine learning
Iman Peivaste, Nima H. Siboni, Ghasem Alahyarizadeh +4
Phase-field-based models have become common in material science, mechanics, physics, biology, chemistry, and engineering for the simulation of microstructure evolution. Yet, they s…
On the higher-order pseudo-continuum characterization of discrete kinematic results from experimental measurement or discrete simulation
Mohammad Khorrami, Jaber R. Mianroodi, Bob Svendsen
The purpose of this work is the development and determination of higher-order continuum-like kinematic measures which characterize discrete kinematic data obtained from experimenta…
Chemo-Mechanical Phase-Field Modeling of Iron Oxide Reduction with Hydrogen
Yang Bai, Jaber Rezaei Mianroodi, Yan Ma +3
The reduction of iron ore with carbon-carriers is one of the largest sources of greenhouse gas emissions in the industry, motivating global activities to replace the coke-based bla…
A geometrically adapted reduced set of frequencies for a FFT-based microstructure simulation
Christian Gierden, Johanna Waimann, Bob Svendsen +1
We present a modified model order reduction (MOR) technique for the FFT-based simulation of composite microstructures. It utilizes the earlier introduced MOR technique (Kochmann et…

Non-linear elastic effects in phase field crystal and amplitude equations: Comparison to ab initio simulations of bcc metals and graphene
C. Hüter, M. Friák, M. Weikamp +4
We investigate non-linear elastic deformations in the phase field crystal model and derived amplitude equations formulations. Two sources of non-linearity are found, one of them ba…
Modeling of grain boundary dynamics using amplitude equations
Claas Hüter, Jörg Neugebauer, Guillaume Boussinot +3
We discuss the modelling of grain boundary dynamics within an amplitude equations description, which is derived from classical density functional theory or the phase field crystal…
