Probabilistic failure analysis of fatigue crack growth using efficient algorithms

摘要

This paper examines the issue of developing efficinet structural reliability assessment capability for local structural details subject to fatigue crack growth from undetected defects. Efficinecy has been a prime directive in the development of the fracture mechanics computer code, FC Code. Progress in computational efficinecy has been realized through solution scheme enhancement, algorithm development and the use of approximate methods as appropriate. Analysis setup efficinecy improvements have been achieved through user input stream minimization and simplification via. increased automation of data input generation and retrieval.
