A. R. C. Markl investigated the phenomenon of fatigue failure of piping during the 1940's and 1950's, and published his results in papers...

A plot of the cyclic stress capacity of a material is called a fatigue (or endurance) curve. These curves are generated through multiple...

Steels and other metals are made up of organized patterns of molecules, known as crystal structures. However, these patterns are not...

Most of the current piping codes use a slight modification of the maximum shear stress theory for flexibility related failures....

To be useful, calculated stresses must be compared to material allowables. Material allowable stresses are related to strengths as...
