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 ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...

In my previous column, I discussed double-shear testing of a single fastener (see “Editor's Picks,” at right). But fasteners also can be subjected to single-shear loading — our subject this time — and ...

The FT4 Powder Rheometer, a universal powder tester, uses patented dynamic methodology, a fully automated shear cell (in accordance with ASTM D7891) and several bulk property tests, including density, ...

This technique is implemented in Textechno’s FIMATEST system. Dr. Ulrich Mörschel, CEO of Textechno, explains: “Up to now, a characterization of the interfacial shear strength according to standards ...

Australian company Swan International aims to conduct flight tests of a laser-based wind-shear detection system being developed for business and general aviation aircraft in the next six months.
