The bio-inspired periodic network design with unit lattice constructed by wavy filamentary microstructures displays potential applications in the fields of bio-integrated devices and tissue engineering, due to its reproduction of the J-shaped mechanics curve that typically observed in biological soft materials. An obvious macroscopic shear deformation can be induced during the uniaxial tension of such kind of periodic soft network materials, which is an important issue for practical application, since that mechanical matching between the network material and target biological tissue is essential for conformal adhesion, while such unusual shear behavior is rarely observed in conventional biological materials. For quantitative evaluation, a theoretical model for nonlinear mechanics of periodic soft network materials is developed and then validated by finite element analysis (FEA) and experiments. The results present a hook-shaped characteristic curve for the shear deformation, whose mechanism is explained via the analysis of microscopic deformation of lattice structure. Based on this model, several factors are taken into account to investigate their effects on the shearing behavior, including horseshoe geometrical parameters, interconnect configuration and lattice topology. The results could provide potential guidelines for the design and optimization of such periodic soft network materials.

由波浪状的细丝微结构构成的具有单元格的生物启发式周期性网络设计，由于其再现了通常在生物软材料中观察到的J形力学曲线，因此在生物集成设备和组织工程领域显示出潜在的应用。在这类周期性软网络材料的单轴拉伸过程中，可能会引起明显的宏观剪切变形，这对实际应用而言是一个重要问题，因为网络材料与目标生物组织之间的机械匹配对于共形粘附至关重要。在常规生物材料中很少观察到异常的剪切行为。为了进行定量评估，建立了周期性软网络材料非线性力学的理论模型，然后通过有限元分析（FEA）和实验进行了验证。结果显示了剪切变形的钩形特征曲线，通过分析晶格结构的微观变形来解释其机理。基于该模型，考虑了几个因素来研究它们对剪切行为的影响，包括马蹄形几何参数，互连构型和晶格拓扑。结果可为此类周期性软网络材料的设计和优化提供潜在的指导。通过分析晶格结构的微观变形来解释其机理。基于该模型，考虑了几个因素来研究它们对剪切行为的影响，包括马蹄形几何参数，互连构型和晶格拓扑。研究结果可为此类周期性软网络材料的设计和优化提供潜在指导。通过分析晶格结构的微观变形来解释其机理。基于该模型，考虑了几个因素来研究它们对剪切行为的影响，包括马蹄形几何参数，互连构型和晶格拓扑。结果可为此类周期性软网络材料的设计和优化提供潜在的指导。
