We study the mechanical behavior of Au nanomeshes (AuNMs) based on finite element analysis (FEA) simulation and deformation tests. The simulated results of mechanical flexibility indicate that polyethylene terephthalate (PET) substrate can release the stress of AuNMs under mechanical stretching and bending, the displacement of stretched AuNMs yields a 2% promotion, and the displacement of bent AuNMs yields a 3.5% promotion under buffering of PET substrate at 5 GPa yield strength of nanoscale Au. The stress and displacement distribution of the AuNMs/PET is demonstrated and analyzed. The further deformation tests of AuNMs under compressive and tensile loading indicate that the simulation data are in good agreement with experimental results. This paper is conducive to understanding the mechanical behavior and corresponding structural response and structural fracture dynamics of AuNMs.

金纳米网的力学性能研究

我们基于有限元分析（FEA）模拟和变形测试研究金纳米网（AuNMs）的力学行为。机械柔韧性的模拟结果表明，聚对苯二甲酸乙二醇酯（PET）基材在机械拉伸和弯曲下可以释放AuNMs的应力，拉伸的AuNMs的位移产生2％的促进作用，弯曲的AuNMs的位移在缓冲作用下产生3.5％的促进作用。 5 GPa纳米金的屈服强度对PET基板的影响。演示和分析了AuNMs / PET的应力和位移分布。AuNMs在压缩和拉伸载荷下的进一步变形试验表明，模拟数据与实验结果吻合良好。
