Machine Learned Material Simulation

This chapter explores the application of machine learningMachine learning techniques in materials simulations, with a focus on three key areas: machine learned interatomic potentials, physics informed machine learningMachine learning for continuum simulations, and physics-enforced graph neural networks. Machine learned interatomic potentials offer a powerful approach to accurately modelModels interaction between atoms in a structure by leveraging machine learningMachine learning algorithms. Physics informed machine learningMachine learning combines domain-specific knowledge and physical equations to enhance the accuracy and efficiency of continuum simulations. Physics-enforced graph neural networks modelModels materials as a graph, while strictly enforcing governing laws as inductive biases. They enable interpretability and generalizability to significantly larger sizes than those trained. These approaches hold great promise for accelerating materials discovery, designing materials with tailored properties, and advancing our understanding of materials behavior. Future research directions include refining and expanding these techniques, exploring their applicability to new materials systems, and developing interatomic potentials that can scale the entire periodic table. Interdisciplinary collaborations will be crucial in pushing the boundaries of machine learningMachine learning in materials science and engineering.
