By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Static and dynamic effective stress coefficient of chalk

Geophysics — 2012, Volume 77, Issue 2, pp. L1-L11

to mechanical strain in the elastic stress regime. The corresponding dynamic effective stress coefficient α is easy to estimate from density and velocity of acoustic (elastic) waves. We studied n and α of chalk from the reservoir zone of the Valhall field, North Sea, and found that n and α vary

Influence of effective stress coefficient on mechanical failure of chalk

Alam, Mohammad Monzurul; Fabricius, Ida Lykke; Hjuler, M.L.; Christensen, H.F.

Proceedings of the 46th Us Rock Mechanics / Geomechanics Symposium — 2012

The Effective stress coefficient is a measure of how chalk grains are connected with each other. The stiffness of chalk may decrease if the amount of contact cements between the grains decreases, which may lead to an increase of the effective stress coefficient. We performed CO2 injection in chalk

Change in Biot's effective stress coefficient of chalk during pore collapse

Alam, M. Monzurul; Fabricius, Ida Lykke

Poromechanics V — 2013, pp. 2395-2403

Biot's effective stress coefficient (α) is a measure of how well grains in the rocks are connected with each other. The amount of contact cements between the grains determines the stiffness of rocks. Change in grain contact occurs during natural diagenesis of sedimentary rock. Contact between
