Fatigue and Fracture Mechanics of Engineering Materials-Part II: Durability and Damage Tolerance (DaDT) for Modern Aircraft & Spacecraft Systems-Applications

This course is a continuation of Fatigue and Fracture Mechanics of Engineering Materials—Part I. Instruction covers more detailed aspects of fracture mechanics, including Elastic-Plastic Fracture Mechanics (EPFM); J-integral; some nonlinear aspects of fatigue crack propagation and fatigue crack growth under large-scale yielding; microstructural basis of fracture toughness, including cleavage and ductile fracture mechanisms; test methods, including fracture toughness testing; load spectrum development and load interaction; aerospace design approaches, including: U.S. Air Force, Navy, Army, and NASA; design of modern aircraft and design for durability; instability and dynamics fracture mechanics; time dependent fracture mechanics, including creep, and environmentally-influenced fracture, including stress corrosion cracking and hydrogen embrittlement; and DaDT tools and processes, probabilistic failure analysis, determination of failure mechanism, and lessons learned in design applications.

The course concludes with brief discussions on the latest work and technologies in these topics, including virtual testing, multi-scale modeling, nanotechnology, nanocomposites, and nonotubes. Case studies and practice problems are also presented.
