An analytical series solution for dynamic stress concentration of lined cavities in a half space under incident plane SV waves was given by using wave function expansion method. The infinite series was cut and calculated under the required precision. The linings includes rigid lining, unlined cavities, flexible lining. The numerical result shows that (1) incident angle has great effect on the dynamic stress concentration factor; (2) the distance between two cavities has great effect on the dynamic stress concentration factor too, and the interaction between two cavities can greatly amplify the dynamic stress concentration when the distance between cavities is closer; (3) the rigidity of lining also has great effect on the dynamic stress concentration which is highest for the rigid lining second for unlined cavities and lowest for the flexible lining.
