Metallographic Study of the Plastic Zone Size Using Magnetic Etching and Visual Observation

Abstract

To understand how fracture of ductile materials occurs, it is necessary to understand how the strain field, especially the plastic zone, develops around the crack as it advances by blunting and tearing [1]. This has been examined in a number of ways experimentally and by calculation. Lacking however, has been a technique, which is highly sensitive to plastic strain in metals, which can also be easily applied to a large area.
