Abstract

The problem of wave propagation in a semi-infinite medium and its interaction with the structure was awalys encountered in the engineering numerical simulation.Artificial boundary conditions of truncated place in semi-infinite domain is the key to ensure accuracy of the calculation results.Adopting fixed boundary hypothesis makes system become a closed system,which clearly contrary to purpose of setting the artificial boundary conditions.Based on ABAQUS software,fixed boundary,viscous boundary, viscoelastic boundary, infinite element boundary and remoted boundary were set respectively,to study vibration response of the simple semi-infinite domain.Results show that under the condition of simple elastic medium,viscoelastic boundary model can get close to the results of actual situation, and also has the advantages of the simple operation, high precision and good stability.
