The latest of the ASTM standards for determining the shear strength and shear stiffness of materials — composite materials in particular — has just been released. The V-Notched Rail shear test was ...

Single-lap shear (SLS) joints are straightforward to manufacture. This makes them especially attractive for testing polymer composite welded joints. Owing to local heating, which is characteristic of ...

This video shows Admet’s adhesive lap joint shear strength test similar to ASTM D1002. Shear joints provide uniform stresses across the bond area thus optimizing the strength of joints. The shear ...

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 ...

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 ...
