II. How To Use ATILA

2.1 Magnetostrictive Rod (4)
VIEW RESULTS


PROBLEM - 2D Cylinder, JM = 50mm L x 6.5mm dia

This example problem illustrates a coil energized with a current source inducing movement in a rod of magnetostrictive material. The magnetostrictive rod has a plane of symmetry normal to its axis. The rod can also be represented using an axisymmetric model. Therefore, only a quarter of the cross-sectional area of the rod needs to be used.
