Fatigue Crack Growth Model RANDOM2 User Manual. Appendix 1: Development of Advanced Methodologies for Probabilistic Constitutive Relationships of Material Strength Models

摘要

FORTRAN program RANDOM2 is presented in the form of a user's manual. RANDOM2 is based on fracture mechanics using a probabilistic fatigue crack growth model. It predicts the random lifetime of an engine component to reach a given crack size. Details of the theoretical background, input data instructions, and a sample problem illustrating the use of the program are included.
