Boundary Element Analysis of Coupled Continuum and Skeletal Structures
This paper presents a new technique for solving coupled continuum and skeletal structures. The technique is based on employing the well-known flexibility and stiffness methods within the boundary element method (BEM). The analyzed problem is divided into: continuum parts, which are modeled using the BEM and skeletal parts which are modeled using the flexibility or stiffness methods. The main idea of the presented technique is to set up a methodology to generate flexibility or stiffness matrices for the continuum parts using the BEM. To do so, several flexibility and stiffness models are developed. The developed technique is tested on three problems. Results are compared to those obtained from the finite element method (FEM) to show the validity of the developed technique. The present technique gains both advantages of the BEM and the FEM as it allows boundary-only discretization for the continuum parts and uses the banded assembly technique of FEM for the overall structure.
