Access a database of rock properties, easily obtaining the results by geographical area or rock type. This issue of TechNews introduces two new equations proposed by Hoek & Diederichs for rock mass modulus. Rocscience also continues the discussion on SSR analysis with the article, "Ready for Prime Time." Add your thoughts on this exciting new approach using our feedback page.

RocData 4.0 - now with a rock properties database!

Facilitating Input Data Breakthroughs
In geotechnical engineering today, numerical modelling capabilities exceed our understanding of soil and rock mass behaviour and the ability to measure input properties. The creation of a database of properties will accelerate progress towards better quantification and understanding of material behaviour.
