Tensile Damage Study of Wind Turbine Tower Material Q345 Based on an Acoustic Emission Method

Xiao Tang et al.

Summary: This study introduces a new method that combines acoustic emission and normalized accumulation parameters to characterize wind turbine tower Q345 steel damage. By analyzing the trends of acoustic emission signal parameters and normalizing the accumulation parameters, the study investigates the damage process and the effects of different stages on these parameters.
