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 ...

President, Wyoming Test Fixtures Inc. In addition to mechanical tests used to determine material properties of composite materials, tests to determine structural properties are commonly performed on ...

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 ...

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 ...
