| Abstract: | Analysis on the behaviors of reflection and transmission of stress shock wave at structure rigid node has been conducted with shock wave theory. Results of analysis show that for a cross node, if the incident stress shock wave comes from the upper pole, shearing stress waves will propagate in both the left and right poles. At the same time, reflected and transmitted compress waves will appear in the upper and lower poles. Formulas to estimate stress and strain parameters behind the waves have been set up. It is found that the ratio of the strength of shearing wave to that of the transmission wave only depends on the material parameters. |
