Fracture Behavior of Stainless Steel

Source

An experimental program has been carried out to characterize the fracture properties of austenitic stainless steel piping and plate material. Characterization was in terms of the J-integral, and several specimen types were tested, including compact specimens, center-cracked panels, and three-point bend specimens.

Several methods of monitoring crack extension were used in the program, including unloading compliance, electrical potential, and acoustic emission in addition to the multiple-specimen heat tinting method used for baseline data. These methods are compared and evaluated in detail.

In addition to determining JIc values for the material, Paris's proposed tearing modulus is evaluated, and various proposed specimen size requirements are discussed.
