Abstract

This paper attempts to model the actuation and sensing behavior of polycrystalline magnetostrictive samples by treating them as composed of multiple grains of single-crystals, each with a different orientation to the loading axis. The texture analysis of a typical cross-section of the sample will be used to estimate the fraction of grains that are close to <100>, <110> and <111> orientation. A simple model based on the law of mixtures will be proposed to represent the behavior of the polycrystal in terms of the behavior of <100>, <110> and <111> oriented single crystals. However, the magnetomechanical behavior along each of the crystallographic directions will be simulated using an energy based model as discussed in Ref. 5 and Ref. 9
