What is Yield Stress and Why does it Matter?
www.pcimag.comcurve to the data, and extrapolating through the stress axis. The intersect on the stress axis gives us our yield stress (figure 2). It is useful here to use a rheological math model, several of which are available on viscometer software packages-such as Brookfield’s Rheocalc and Wingather Software-to quantify the intersect. In the sample ...

The detailed analysis methods are discussed below. GLASS TRANSITION FROM THE STORAGE MODULUS The glass transition from the storage modulus onset is typically the lowest T g measured by DMA and rheological ...
