Abstract

An equivalent model is proposed for the prediction of the mechanical behaviors of a honeycomb core with thick cell walls, including the calculation of failure strength. The method was derived from the homogeneous method used to investigate the mechanical behaviors of composite sandwich structures. We validated the method’s utility through the finite element method and experimentally. A parametric analysis was performed to examine the mechanical properties of a composite sandwich structure with thick cell walls using the proposed method. These results were used to compile information about the mechanical characteristics of the structure for aerospace applications. In conclusion, the method is demonstrated to be well suited for its intended applications due to its relative simplicity and computational efficiency.

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.
