An Optimal Method for Damage Probability Imaging of Composite Materials

摘要：

　　Damage in composites can change the propagation characteristics of Lamb waves in structures.Probabilistic imaging method can achieve damage location based on the fact that different paths sense different of the damage in the Composite structure.In this paper,an improved probabilistic imaging algorithm is studied.The extraction method of damage factor was improved.It can effectively eliminate the influence of environmental factors on damage probability imaging.The impact test in the composite box shows that the accuracy of damage location is improved from 68%to 82%.
