Method for constructing three-dimensional negative poisson ratio structure based on regular tetrahedron frame

The invention belongs to the field of mechanical metamaterial structure design, and relates to a method for constructing a three-dimensional negative poisson ratio structure based on a regular tetrahedron frame; the method comprises the following steps: designing geometric parameters of hexadecahedron units, stacking the hexadecahedron units with specific parameters according to a mode of forming a specific dihedral angle between layers, and finally constructing a repeated regular tetrahedron frame; the space stacking strategy can ensure formation of a three-dimensional negative poisson ratio structure, and poisson ratio behaviors of the three-dimensional negative poisson ratio structure change regularly according to different configurations of thickness parameters of hexadecahedron units; according to the design, quantitative regulation and control of the negative Poisson's ratio property of the material are realized while the force performance of the material is enhanced by the negative Poisson's ratio structure, so that application scenes with different negative Poisson's ratio requirements are met.

Novel foam concrete wall body building block

The invention discloses a novel foam concrete wall body building block. The novel foam concrete wall body building blocks comprises a brick body, the brick body is provided with transverse channels ofarc-shaped grooves and vertical channels of circular holes, the brick body is a middle to low dry density foam concrete material, the outline of the brick body is of a rectangular shape, and two sides of the front and rear sides of the brick body are all rectangular surfaces; and arc-shaped brick body connecting seams are arranged on the positions of the left and right sidesalong center lines correspondingly, the arc-shaped groove transverse channels are arranged on the position of two surfaces of the upper and lower surfacesalong center lines, and the vertical channels of the three circularholes penetrate the upper and lower end surfaces of the brick body are formed in the brick body. According to the novel foam concrete wall body building block, through the design of the structure andshape of the building block, when the building block is used in wall body masonry, vertical and horizontal channels are formed in the wall body naturally, after the vertical and horizontal channels are poured with small stone concrete, the compressive strength of the middle to low dry density building block is offset, the bearing capacity of the wall body is improved, the integrity is reinforced,not only the heat insulation of the foam concrete block is fully reflected, and meanwhile, the application range of the foam concrete block is expanded as well.
