Abstract
The phase-field method enables simulating the spatiotemporal evolution of the coupled physical-order parameters under externally applied fields in a wide range of materials and devices. Leveraging advanced numerical algorithms for solving the nonlinear partial differential equations and scalable parallelization techniques, the phase-field method is becoming a powerful computational tool to model and design devices operating based on multiple-coupled physical processes. This article will highlight examples of applying phase-field simulations to predict new mesoscale physical phenomena and design new-concept magnetomechanical devices by identifying the desirable combination of the composition, size, and geometry of monolithic materials as well as the device structure. A brief outlook of the opportunities and challenges for modeling and designing magnetomechanical devices with phase-field modeling is also provided.
期刊介绍：
MRS Bulletin is one of the most widely recognized and highly respected publications in advanced materials research. Each month, the Bulletin provides a comprehensive overview of a specific materials theme, along with industry and policy developments, and MRS and materials-community news and events. Written by leading experts, the overview articles are useful references for specialists, but are also presented at a level understandable to a broad scientific audience.
