Analysis of three-dimensional inhomogeneous composite bodies using the boundary integral method
- Boston Univ., MA (United States)
A formulation of the Boundary Integral Method was developed for the elastostatic analysis of composite inhomogeneous bodies, those in which the material properties vary as a function of position. Using the inhomogeneous form of the Navier Equation for elastostatics, we derived a Boundary Element method that incorporates the material inhomogeneity as a body force of an effective homogeneous boundary value problem. Since the body force is a function of the internal stresses, an iterative procedure was employed to calculate unknown displacements and stresses. Numerical examples were produced and compared to analytic solutions for several cases. This formulation can be used to study interfacial regions in smart materials, thin film/substrate systems in electronic packaging and layered structural composites.
