| Abstract: |
| A new structural damage identification method based on energy density was put forward based on energy finite element method. Basic building blocks, beams of engineering structures were taken as research objects and energy density mutations as the damage identification index to simulate the damage structure. The most common form of structural damage, cracks beam damage identification test was carried out. The results showed that the damage identification method proposed is applicable to medium and high frequencies, sensitive to small defects of the structure; it has the advantages of simple operation, high accuracy,and without the complexity of data processing; it has high engineering values. |
