| In the elastic dynamics range, the scattering of multiple debonding interface cylindrical elastic inclusions by SH-wave is researched by complex variable method and the Green's Function method. To solve this problem, two specific Green's Functions under specific boundary are constructed firstly, which are the scattering of out-plane line source load by multiple cylindrical elastic inclusions in half space and the scattering of out-plane line source load by multiple semi-cylindrical canyons in half space. Then divide the whole space into two parts along the interface with the method of dividing the district. And a standing wave in each inclusion and the scattering waves in particular form by multiple semi-circular boundaries can be constructed seperately. Re-conjuct the two part along the interface together and establish integral equations about the Green'Fuctions and unknown funtions about external forces with the continuous condition of the displacement and stress around the common boundary. Use numerical method to solve the equations. In the end, as examples, numerical results of dynamic stress concentration factor around the inclusions and the influences of the incident wave on difference parameters of mediators are presented and discussed.In addition, some examples are given and results of dynamic stress concentration factor around the inclusion and the ground vibration at the horizontal surface are presented and discussed after constructing the Green'Fuction of the scattering of out-plane line source load by multiple cylindrical elastic inclusions in half space. And do furher researth in the scatering of SH-wave by multiple debonding interface cylindrical elastic inclusions and linear cracks originating at the debonding tip near two-phase mediums, as well as the scatering of SH-wave by multiple debonding interface cylindrical elastic inclusions and III mode of interface cracks by using the Green'Fuction. In the end some results of dynamic stress intensify factor are discussed. |
