Modularized assembly type auxetic superstructure based on mortise and tenon connection

According to the modular assembly type auxetic superstructure based on mortise and tenon connection, the overall structure can be separated into different modules through structural shape design through mortise and tenon connection, effective support can be formed between the modules, and then a whole is formed, and the modular assembly type auxetic superstructure based on mortise and tenon connection is inspired by the modular assembly type auxetic superstructure based on mortise and tenon connection. The invention particularly relates to the fields of auxetic materials, earthquake resistance, vibration isolation, energy absorption protection and the like. The structure is composed of a restraining unit and a restrained unit. By overcoming the limitation that a traditional auxetic structure is integrally produced through 3D printing and laser cutting technologies, compared with the prior art, the method has the advantages that for any two-dimensional microstructure form, the two-dimensional microstructure fo
