NASGRO 3.0

NASGRO 3.0

NASGRO 3.0

(OP)
I am teaching myself to use NASGRO. I have version 3.0.
I have had success running the program for simple problems ie cracks in skins under pressure loading.
I want to move on to problems with more involved loading but inputing the spectrum is causing problems. I would appreciate it if someone had some input files for problems involving G-A-G cycles that I could get a copy of so that I could see how the data is input into the program.
Your help would be gratefully received.

Thanks
CS

RE: NASGRO 3.0

AFGROW has nothing to do with NASGRO. Many of the crack solutions in NASGRO are in AFGROW; however, almost all of these solutions are in the open literature. So I think it is in error to say that NASGRO is an integral part of AFGROW.

There is something from NASGRO in AFGROW--the material crack growth rate database in NASGRO is one of the options in AFGROW, which has several options for crack growth rates--your own curve, NASGRO's curves, Forman equation, Walker equation, and Harter-T method.

Besides, up until last December (2007), AFGROW was free to users, fully funded by US taxpayers; it will cost something (unknown) in the future.

What's the going rate for entrance into the NASGRO consortium (which gives you access to this formerly free software) now?
