Glass transition temperature of polymers

The glass transition temperature is the temperature at which an amorphous or semicrystalline polymer transitions from a glass-like, brittle state into a rubber-elastic state. In this range, the molecular mobility of the polymer chains changes drastically, which leads to a change in the mechanical properties. In contrast to crystalline substances, amorphous materials do not have an orderly crystal lattice, but rather unordered molecular chains.

Calculating shear strengths and tensile strengths for screws

Shear strength and tensile strength are two important parameters for selecting and using screws. Screws are used to connect components in a friction-locking manner and to withstand mechanical loads. In order to ensure that screws meet the required strength requirements in a given application, it is important to know what shear strength and tensile strength are and how they are calculated.

Understanding bearing damage – Causes, failure mode and prevention

Rolling bearings are robust and reliable components in mechanical engineering and custom machine construction. Under certain conditions, however, bearing damage to these widely used machine elements can occur, usually resulting from unusual behavior during operation. In the worst case, bearing damage can result in a complete failure of the rolling bearings, which can result in unwanted downtime. Therefore, it is important to detect the first signs of rolling bearing damage early on and to remedy their causes. In this article, we discuss the symptoms of bearing damage, its causes and typical failure modes.
