摘要: Mimicking natural structures has been highly pursued recently in composite structure design to break the bottlenecks mechanical properties of traditional structures. Bone a remarkable comprehensive performance strength, stiffness and toughness, due intricate hierarchical microstructures sacrificial bonds within organic components. Inspired by strengthening toughening mechanisms cortical bone, new biomimetic structure, with designed progressive breakable internal construction mimicking bond, is proposed this paper. Combining bio-composite staggered plate bond-mimicking construction, our can realize tunable superior toughness. We established constitutive model representative unit cell investigated its through theoretical analysis, as well finite element modeling (FEM) simulation. Two relations, respectively describing elastic modulus decline ratio toughness promotion, are derived functions geometrical parameters material parameters, validated hope that work lay foundation for high design, provide ideas development strategies bio-inspired
