... fluctuations. This article begins with an overview of fatigue properties and design life. This is followed by a description of the two approaches to fatigue, namely infinite-life criterion and finite-life criterion, along with information on damage tolerance criterion. The article then discusses...

...., multiaxial yield criteria). One failure mode theory is the Rankine (or maximum normal stress) criterion, where the maximum principal stress is used. The other is the Tresca theory based on the maximum shear stress. The Rankine criterion holds that inelastic deformation at a point begins when the maximum...

... project. Frequently, principal stresses and maximum shear stresses are important to the designer because both are used in common failure expressions to calculate maximum load capability (e.g. multiaxial yield criteria). One failure mode theory is the Rankine (or maximum normal stress) criterion, where...

... Certain materials, such as body-centered cubic steels, may have an endurance or fatigue limit, typically denoted S e , which is a stress level below which the material is considered to have an “infinitelife. For many practical applications, this infinite life is usually considered to be at 1 million...

Replacement parts have been designed to provide larger margins of safety under ultimate and limit load conditions and infinite fatigue life using 300M steel...

... and collect a quantifiable output on galling and galling severity by using only visual assessments ( Ref 79 ). In an effort to remove the subjectivity of a visual assessment of galling, a friction-based criterion ( Ref 80 ) can be used to define galling based on the critical friction level and/or by employing...
