| Abstract: | The paper reviews the propagation mechanism of stress wave and the advantages, disadvantages and working processes of stress wave wood non-destructive testing technology. It also introduces stress wave wood testing facilities, which are commonly used in the field of wood non-destructive testing, and analyzes their characteristics. The progress of this technology research is summarized and analyzed from three aspects of mechanical property testing, internal defect detection and factors affecting stress wave propagation velocity. The development prospects of stress wave wood non-destructive testing technology is prospected, in order to provide references for the further research in this field. |
