Abstract
The sintered nano-silver has been widely concerned by the industry in the field of electronic packing. Researches on sintered nano-silver have mostly focused on individual tensile or compressive loading conditions. In the paper, the mechanical properties of sintered nano-silver components were investigated under the periodic tensile and compressive loads by molecular dynamics method. The influence of periodic load on it was studied, and the difference between sintered and unsintered nano-silver under the same condition was analyzed and compared. Under different periodic loads, the different number of periods do not affect the initial potential energy, and their maximum potential energy peaks are not different. Under the periodic load of different tensile rates, the maximum potential energy increases with the increase of the tensile rate. The yield stress of sintered nano-silver is higher than that of unsintered nano-silver under different periodic loads and different tensile rates. The results show that the sintering process improves the mechanical properties of nano-silver components.
