摘要：

In this paper, the magnetoelastic coupling effect in an infinite soft ferromagnetic material with a crack is analyzed. The nonlinear effect of magnetic field upon stress and the effect of the deformed crack configuration are taken into consideration. The coupling field is determined in the deformed configuration by regarding the deformed crack Lis ail elliptical cylinder with its geometric coefficients, which are determined from a set of algebraic equations deduced from the displacements. The magnetic and stress fields near the crack tip are discussed for the case where both of the magnetic loading and the mechanical tension are present. (C) 2002 Elsevier Science Ltd.
