META STRUCTURE HAVING ZERO ELASTIC MODULUS SECTION AND METHOD FOR DESIGNING META STRUCTURE HAVING ZERO ELASTIC MODULUS SECTION

WIPO Patent Application WO/2022/004909

A1

Provided in one embodiment of the present invention are: a meta structure having a zero elastic modulus section, the structure being capable of having uniform stress in a certain deformation section; and a method for designing the meta structure having a zero elastic modulus section, wherein the meta structure having a zero elastic modulus section comprises a first unit and a second unit. The first unit is formed in a structure enabling buckling and includes a section having a negative elastic modulus in a stress-strain rate relationship. The second unit is arranged to be adjacent to the first unit and includes a section having a positive elastic modulus in the stress-strain rate relationship. The meta structure has a zero elastic modulus in a preset target deformation section because of a combination of the negative elastic modulus of the first unit and the positive elastic modulus of the second unit.
