ORMAS is a free software for determining rock mass strength parameters, based on the Generalized Hoek-Brown failure criterion. The first version of this program was written in matlab as part of a college project in my previous life and recently I decided to rewrite it by java, html as well as php to make it available directly from the internet.
ORMAS is non-commercial and free to use. If you have questions or comments, please contact me at [email protected]. Visit my personal web page to find out about the other free software or my experiences and research interests.
