Abstract

Joint analysis of acoustic emission (AE), strain diagrams, structures and fractures is used to study the kinetics and mechanisms of fracture of specimens, fragments and unit-cast railroad car solebars from steel 20GL in different strength states. A system of AE monitoring of damage of solebars during motion of the train is developed and applied. The crack sizes are determined by measuring peak amplitudes of acoustic emission.
