Dynamic Stress Distribution of Arbitrarily Arranged Deep Cavities Subjected to Incident Plane P Waves by Multiple Scattering Method
Abstract Based on the elastic wave propagation and scattering theories, it is introduced acoustical and electromagnetical multiple scattering solutions. With wave function expansion and coordinates translation methods, it is solved the every order of scattering complex coefficients with boundary conditions. The iteration relation of high order to lower order of scattering coefficients is established, the multiple scattering wave and total wave field are determined as well. It is innovatively calculated the elastic wave multiple scattering and dynamic stress response problems of arbitrarily arranged deep cavities subjected to incident P waves. The numerical example shows the value of Dynamic Stress Concentration Factor (DSCF) which the cavities group is arranged as hexagon is approximately the same as the ones linearly arranged meanwhile the separation between cavities is narrower than the former one.
