Decoupled determination of magnetostriction and inverse magnetostriction

摘要

Rapid calculation of magnetostriction effects can consist of calculating a stress field and a magnetic field in a structure by determining a magnetic field on the magnetic mesh, determining a magnetostriction from the magnetic field, applying the magnetostriction to the mechanical mesh, determining a stress field on the mechanical mesh, determining an inverse magnetostriction from the stress field, applying the inverse magnetostriction to the magnetic mesh, and determining a new magnetic field on the magnetic mesh by accounting for the inverse magnetostriction. Calculations can be based on data representing a structure, including a magnetic mesh, a mechanical mesh, and a plurality of material properties. After calculation is completed, data characterizing the calculated stress field and magnetic field for the structure can be provided as output. Related apparatus, systems, techniques, methods and articles are also described.
