摘要

相场法能够模拟各种材料和设备在外部施加场作用下耦合物理阶参数的时空演变。利用先进的数值算法求解非线性偏微分方程和可扩展的并行化技术,相场法正成为基于多重耦合物理过程的设备建模和设计的强大计算工具。本文将重点介绍应用相场模拟来预测新的中尺度物理现象,并通过确定整体材料的成分、尺寸和几何形状以及器件结构的理想组合来设计新概念磁力学器件的实例。此外,还简要展望了利用相场建模对磁机械装置进行建模和设计的机遇与挑战。

Design of new-concept magnetomechanical devices by phase-field simulations

Design of new-concept magnetomechanical devices by phase-field simulations

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.
