Abstract

For the stress analysis of ultra-thin structures, the modeling of conventional domain solution techniques will require a tremendous amount of domain elements, whose aspect ratios must have orders close to unity. Due to this reason, past research work by the finite element method seldom investigated ultra-thin layers of composites. This article proposes a boundary element approach that may yield accurate stress analysis by coarse mesh-modeling for ultra-thin layers of multilayered composites subjected to inertial loads. In this article, the nearly singular integrals in the boundary integral equations for displacements and strains are analytically integrated. The algorithm has been successfully implemented in an existing computer program based on quadratic elements.
