| Abstract: | Based on the theory of the one dimension elastic wave,the bar gauge was used to measure the stress wave parameters in concrete.The bar's length,diameter and material quality were discussed,the model of the concrete subjected to blast load was established,and the experiment system was set up.The experimented results show that the design of the bar gauge is correct,its parameters satisfy the measurement requirements. |
