Inertia welding is a well-established, friction-based, solid-state joining process. Many different applications use this welding process, ranging from aircraft engine parts to air bag inflators to hand tools. Process parameters associated with inertia welding (spindle speed, welding force, inertia, and displacement) have been widely studied since the process gained traction in the late 1960s. One...

A polymer can act rubbery or glassy depending on its temperature or rate of deformation, such as from an impact. This is important for medtech devices that are stored at low temperature, vibrate, or are required to pass drop testing. In general, the quicker the polymer is impacted, the more brittle it acts and the...

All bodies at finite temperature emit electromagnetic radiation. The hotter the object the more energy it radiates and the shorter the wavelength it emits. Room temperature objects emit in the long wavelength infrared (LWIR) spectrum range. The ability to produce a temperature map of an object is very useful in nondestructive evaluation (NDE). Static IR...
