Selective Laser Melting is an additive manufacturing (AM) process which uses high-powered lasers to rapidly melt and solidify metal powder into three-dimensional structures. The SLM process is highly complex and can have undesirable results such as stochastic defect formation and non-equilibrium microstructures. To fully…
The microstructural heterogeneity affects the macroscale behavior of materials. Furthermore, the loading at the macroscale changes the microstructural morphology. These structure-property relations are often modeled using multiscale approaches such as the finite element method (FEM). However, multiscale FEM requires many calculations at the local…
The macroscopic properties of materials that we observe and exploit in engineering applications result from complex interactions between physics at multiple length and time scales: electronic, atomistic, defects, domains etc. Multiscale modeling seeks to understand these interactions by exploiting the inherent hierarchy where the…
Lithium-ion (Li-ion) batteries have become the main power source of electric vehicle (EV) in recent years. In the event of crash, debris can penetrate the battery and cause short circuit, thermal runway or even explosion. Such instances put the passengers at risk. In this…
The view of materials as systems has paved the path for a hierarchical approach to materials-by- design. The emergence of powerful cyberinfrastructure have created unprecedented opportunities to develop data-driven approaches to material design and discovery. In the context of predicting microstructure-sensitive mechanical behaviors of…
