利用激光超声测量H型钢梁的残余应力

Measurement of Residual Stress in H-shaped Steel Beam Using Laser Ultrasonic

介绍了利用激光超声和瑞利波测量残余应力的方法及主要的测量装置 ,描述了采用这种方法对轧制H型钢梁残余应力的测量过程 ,并对测量结果进行了分析 .

A nondestructive measurement technique of residual stress using laser ultrasonic and Rayleigh waves is described, and the main devices used in the technique are also introduced. The technique is applied to measure the residual stress in a H_shaped steel beam. The result is reasonable.
