42688-AC9 The Role of Capillarity in Mobilization of Disaggregated Materials from Collapsed Perforations
Narrative progress report for Period 9/1/2008 to 8/31/2009
This is the no-cost extension period. We have accomplished the following: refining the tensile apparatus, conducting tensile strength tests for loose sand and consolidated sand stone, and constructing a new theory for description tensile strength due to capillarity. The major results are reported in a paper entitled "Tensile Strength of Unsaturated Sand," and the paper is scheduled to be appeared in the 2009 December issue of Journal of Engineering Mechanics.
The fund for this period is used to partially support Ph.D. student Murat Kaya for executing the detailed tasks.
