Crack propagation analysis of WECS (wind energy conversion system) components using the LIFE2 computer code

Conference ·

;

The LIFE2 code is a fatigue/fracture analysis code that is specialized to the analysis of wind energy conversion system components. It is a PC-compatible FORTRAN code that is written in a top-down, modular format. This paper discusses the additions to the code that permit WECS components to be analyzed using linear fracture mechanics. To illustrate the capabilities of the numerical techniques employed here, two example problems are presented. 8 refs., 7 figs.
