Dugdale Plastic Zone of a Penny-shaped Crack in a Magnetoelectroelastic Material Under Axisymmetric Loading

摘要：

　　The Dugdale plastic zone ahead of a penny-shaped crack in a magnetoelectroelastic material,subjected to electric,magnetic and axisymmetric mechanical loadings,is evaluated analytically.Hankel transform is employed to reduce the mixed boundary value problem of the penny-shaped crack to dual integral equations,which are solved exactly under the assumption of electrically and magnetically permeable crack surface conditions.An exact solution of the mixed boundary problem is obtained to predict the relationship between the length of the plastic zone and the applied loading.
