Computing Remaining Fatigue Life Under Incrementally Updated Loading Histories

After manufacture, every military vehicle experiences a unique history of dynamic loads, depending on loads carried, missions completed, etc. Damage accumulates in vehicle structures and components accordingly, leading eventually to failures that can be difficult to anticipate, and to unpredictable consequences for mission objectives. The advent of simulation-based fatigue life prediction tools opens a path to Digital Twin based solutions for tracking damage, and for gaining control over vehicle reliability. An incremental damage updating feature has now been implemented in the Endurica CL fatigue solver with the aim of supporting such applications for elastomer components. The incremental updating feature is demonstrated via the example of a simple transmission mount component. The damage state of the mount is computed as it progresses towards failure under a series of typical loading histories.

Nonferrous Metals Bundle

Anytime
Nonferrous materials are malleable, are non-magnetic, and have no iron content which gives them higher resistance to rust and corrosion. The following five on-demand courses are included in the Nonferrous Metals bundle.  Each course is approximately one-hour in duration. See Topics/Outline for additional details. Introduction to Physical Properties  This course provides an an overview of manufacturing materials and their physical properties, including thermal, electrical, and magnetic properties and introduces volumetric characteristics, such as mass, weight, and density.
