Abstract

In this paper, we propose an isogeometric boundary element method for the homogenization of linear viscoelastic composites. We extend the simple-domain boundary element method, originally designed for elastic composites, to linear viscoelastic composite. To reduce computational cost, the multi-domain-based simple-domain boundary element method is also presented. Based on a simple homogenization strategy, we use the Prony series to approximate the macroscopic effective relaxation tensor. The isogeometric boundary element method is particularly suitable for homogenization because it has the advantages of boundary-only discretization, easy implementation of periodic boundary conditions, exact geometric representations, and high-order continuity. The performance of the proposed method is demonstrated through 2D and 3D numerical examples.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
