Abstract: | In this paper, the dynamic response of an orthotropic plane with multiple cracks is analyzed analytically. The anti-plane impact loading condition is considered. The dislocation solution is utilized to derive integral equations for multiple interacting cracks with any location and orientation in an orthotropic plane. These equations are solved numerically thereby obtaining the dislocation density function on the crack faces and stress intensity factors of cracks. Numerical results are presented to illustrate the influences of parameters such as cracks geometry and orientation on the dynamic stress intensity factors. |
