The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

Substances with a yield stress only start to flow once the outside forces acting on them are larger than their internal structural forces. Below the yield point the substance shows elastic behavior ...

WEST LAFAYETTE, Ind. - Soybean producers can easily get an idea of the yield potential of their crops with a Purdue Extension soybean specialist's calculation method. Soybean yield potential is built ...
