INFLUENCE OF HIGH PRESSURE AND TEMPERATURE ON YOUNG MODULUS AND POISSON RATIO VALUES FOR SELECTED ROCK TYPES
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2011, Vol 446, Issue 446
Abstract
The study presents and discusses the influence of high pressure and temperature on changes of the value of static Young modulus (Est) and static Poisson ratio (st) for selected lithological types. The values of these material constants are changing with increasing pressure and temperature in different ways depending on lithological types. For sandstones a general trend is observed – the value of Young modulus increases with depth. Similar tendency might be observed in case of granites. Changes of pressure and temperature do not affect dolomites significantly. For anhydrite high variations of Young modulus are observed depending on depth. For basalts at high depth (2000 m) increasing trend inverts into decreasing. Static Poisson ratio (V[sub]st[/sub]) does not have clear trends. The values of the ratio do not depend on temperature and depth as well.
