Research on acoustic emission signal processing of concrete beam in fracture experiment based on the HHT

摘要：

　　In this paper,the fracture process of concrete beam was monitored by acoustic emission,and the acoustic emission signals of the concrete beam in fracture process were transformed by Hilbert-huang,four different failure stages could be seen in the fracture process of concrete beam through the Hilbert spectrum diagram and the effectively monitoring of failure process of concrete beam was realized.
