AI enhanced finite element multiscale modelling and structural uncertainty analysis of a functionally graded porous beam
Da Chen, Nima Emami, Shahed Rezaei +5
The local geometrical randomness of metal foams brings complexities to the performance prediction of porous structures. Although the relative density is commonly deemed as the key…
Modeling and simulation of sintering process across scales
Min Yi, Wenxuan Wang, Ming Xue +2
Sintering, as a thermal process at elevated temperature below the melting point, is widely used to bond contacting particles into engineering products such as ceramics, metals, pol…
Variational quantitative phase-field modeling of nonisothermal sintering process
Timileyin David Oyedeji, Yangyiwei Yang, Herbert Egger +1
In this work, we present a variational and quantitative phase-field model for non-isothermal sintering processes. The model is derived via an extended non-diagonal phase-field mode…
A thermo-mechanical phase-field fracture model: application to hot cracking simulations in additive manufacturing
Hui Ruan, Shahed Rezaei, Yangyiwei Yang +2
Thermal fracture is prevalent in many engineering problems and is one of the most devastating defects in metal additive manufacturing. Due to the interactive underlying physics inv…
A mixed formulation for physics-informed neural networks as a potential solver for engineering problems in heterogeneous domains: comparison with finite element method
Shahed Rezaei, Ali Harandi, Ahmad Moeineddin +2
Physics-informed neural networks (PINNs) are capable of finding the solution for a given boundary value problem. We employ several ideas from the finite element method (FEM) to enh…
Phase-field modeling of paramagnetic austenite-ferromagnetic martensite transformation coupled with mechanics and micromagnetics
Dominik Ohmer, Min Yi, Oliver Gutfleisch +1
A three-dimensional phase-field model is proposed for simulating the magnetic martensitic phase transformation. The model considers a paramagnetic cubic austenite to ferromagnetic…
