|Issue Date:||2004||Publisher:||American Institute of Aeronautics and Astronautics, Inc.||Source:||Collection of Technical Papers - AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2004, Volume 4, Pages 2543-2552||Abstract:||A parallel processing methodology is developed and applied to improve the efficiency of probabilistic fracture mechanics analyses of gas turbine disks subject to metallurgical defects. A parallel processing spatial decomposition approach using a network of workstations and personal computers is described whereby each computer analyzes a region of the disk. The individual analyses are then combined to obtain the probability of fracture of the total disk. Practical implementation issues of job scheduling and optimum file size are addressed. Numerical applications are presented that demonstrate the methodology. This capability can significantly facilitate efficient evaluations of gas turbine rotor designs.||URI:||http://ktisis.cut.ac.cy/handle/10488/7790||ISSN:||0273-4508||Rights:||© 2004 American Institute of Aeronautics and Astronautics, Inc.|
