Fracture Resistance of Structural Alloys
MetadataShow full item record
FRACTURE MECHANICS is a multidisciplinary engineering topic that has foundations in both mechanics and materials science. From the perspective of a metallurgist, fracture mechanics often emphasizes mathematical mechanics, where the primary focus is on analytical methods. However, the microstructural aspects of fracture mechanics (quantified in terms of various measures of fracture toughness such as K Ic, K c, or K Id) is important for several reasons. The article begins with brief coverage on basic fracture principles, followed by material examples. Included in this text are examples of steels, aluminum alloys, titanium alloys, cermets, and composites. Three instances of 6061.
