Adjustable indentation and vibration isolation performances of nacre-like metamaterial

Along with the living environment, organisms have evolved structures that adapt to specific environments and better mechanical properties. Bioinspired materials learn from nature improve their properties by imitating structure of organisms. Based on 4D printed shape memory polymer bioinspired design method, this research proposes a soft hard phase hybrid metamaterial effect programmable Compared traditional nacre-like materials, adjustable characteristics properties, impact resistance, low-frequency vibration isolation. First, based constitutive relation SMP (Shape polymer) material its numerical simulation, an intelligent is designed. Subsequently, isolation behavior adjustability performance multi-scale metamaterials are explained experiments. Finally, functional mechanism deformation described. The these has broad application prospects in fields protection absorption.
