Determination of Flow Curves under Equibiaxial Stress Conditions
Key Engineering Materials, 2012 Three experimental methods have been used to establish flow curves for a low carbon steel under biaxial stress conditions: the hydraulic bulge test, the stack compression test and the biaxial tensile test. The individual tests are discussed and the results for a DC06 IF steel grade compared.

Determination of the Soil Water Retention Curve Using the Flow Pump [PDF]
Rem: Revista Escola de Minas, 2015 AbstractReliable measurements of the Soil Water Retention Curve, SWRC, are necessary for solving unsaturated flow problems. In this sense, a method to obtain the SWRC of a silty sand using a flow pump, as well as details about procedures and some results, are herein presented.
