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 ...

Flow of a number of complex fluids like surfactant mesophases, emulsions and network forming polymers is induced only when the applied stress is more than a specific value, which is called the yield ...

Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength of internal threads or the bolt’s ...
