It is possible to characterize the shear thinning behavior of thermoplastic materials using a Flow Rate Ratio (FRR) test method in an extrusion plastometer (melt indexer). This test method, “Procedure ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...

The Wind Load Shear Wall Calculator is a shear wall design calculator for the iPhone or iPod Touch. It is a tool for engineers, architects, and builders, as well as students to design shear walls to ...

In my previous column, I briefly cited the Short Beam Shear (SBS) test method as a much more attractive interlaminar shear test method than the double-notch shear test method. The primary attraction ...

As the name implies, the Short Beam Shear test subjects a beam to bending, just as flexural testing methods do, but the beam is very short relative to its thickness. For example, ASTM D 2344 1 ...

The term thixotropy consists of the Greek words "thixis" (touch) and "trepein" (to turn). It means change or transition due to mechanical load. In rheology thixotropic behavior is defined as ...

Shear walls are walls specifically designed to resist lateral loads, transferring the load from the wall above to the wall below and, ultimately, out through the foundation. This is a critical role in ...
