Laboratory Experimental Studies of Dummy Instrument for Ultrasonic Testing of Stresses in Rail Bars

摘要

The article discusses the results of laboratory experimental studies in the field of development of monitoring methods of stressed state in continuous rails on the basis of acoustoelasticity using laser ultrasonic sources. The obtained results were applied for determination of constants interrelating acoustoelastic properties of rail steel depending on metal structure; the errors of their measurement are also given.
