Abstract

Motivated by the attractive mechanical properties and the wealth of biological genetic information carried by the DNA structures, we proposed a novel B-form DNA Dual Helix Metamaterial (DHM) in this paper, which has programmable longitudinal wave propagation properties. A dual helix DNA metamaterial is first designed to follow the natural geometry of the B-form DNA structures. To mimic the programming of genetic information in DNA, four types of mass blocks, each made from different materials (i.e., iron, aluminum, nylon, and foam), are selected to serve as the base pairs within the 3D-printed dual helix frame. The elastic wave propagation properties of the DHM, which have unitary mass blocks of different materials, are first compared to comprehend the encoding characteristics of the dual helix metamaterials. After that, a mixed model of DHM, comprising randomly arranged mass blocks, is used to reveal the extensive programmable features for elastic wave propagation. In addition, the influence of the structure parameters, including the helix’s size and the base plates’ thickness, are investigated. Finally, a laser vibrometer system is used to validate the analysis of the proposed elastic metamaterial, experimentally. The investigation in this paper paves the way for broadband low-frequency vibration isolation for engineering applications.

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.
