Abstract

The article uses and compares effects of two artificial boundary methods when they are applied to problems of stress waves in NMM methods. Starting from D'Alembert's solution, the article finds another way to exerting viscous boundary. By modeling in NMM method and exerting fixed boundary, viscous boundary and transmitting boundary in the research of stress wave propagating in a thin rod, after observing the stress, displacement and velocity, it is discovered these artificial boundaries both have the ability to absorb the stress wave. Especially,the 2nd transmitting boundary performs a great absorbing efficiency of 99.6%.
