An overview of fatigue failure and how it affects mechanical systems. How FEA software enables engineers to predict fatigue failure points on structural designs, before the manufacturing process. From ...

Purely static loading is rarely observed in modern engineering components or structures. By far, the majority of structures involve parts subjected to fluctuating or cyclic loads, often resulting in ...

When designing printed circuit boards (PCBs), keep in mind the major causes of electronic failure: thermal cycling, vibration, and mechanical shock and drop. You can perform a variety of physical ...

Achieving high fatigue strength in the 3D-printed NTD-Al alloy (AM NTD-Al). (A) Number of cycles to failure plotted against the maximum stress of AM NTD-Al, compared with other reported 3D-printed ...

The turbulent air above a wildfire is punishing to aircraft structures. The excessive and frequent loads place an inordinate number of loading cycles on an aircraft, leading to accelerated crack ...

A detailed metallurgical examination of a 7/8-in. and a 1-in. sucker rod revealed corrosion fatigue had caused their failure. The 7 to 8-in. rod had failed after a few months of service while the 1-in ...

Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...

The actions of humans, machinery, ventilation and heating systems, and road or rail traffic can cause many vibrations. Although these vibrations have little effect on occupants, equipment used in ...
