NASGRO 3.0 1

[compositestress]

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

Try AFGROW

http://www.siresearch.info/projects/afgrow/index.php

that used NASGRO as built in intgral part of it.

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?

The NASGRO consortium is now managed by Southwest Research Institute.
