%X With the continuity conditions of stress and displacement on material interface,complex potentials solutions for a bi-material infinite plate with an elliptical inclusion under uniaxial tension are given.The stress field of a bi-material infinite plate with an elliptical inclusion and a semi-infinite interface crack are given on the base of the complex potentials solutions obtained above.And the corresponding stress intensity factor K is given.The influences of the position,the shape,material property,and different material combinations of inclusion on the stress intensity factor K are calculated.The results indicate that the distance of inclusion from crack tip and the property of inclusion have remarkable influence on the stress intensity factor K,and these influences vary notably with different material combinations,whereas the shape of inclusion has little influence on K.When the inclusion is soft,the shield effect is occurred for K; conversely,it is inverse shield.
