Fatigue Essentials header

Fatigue Essentials is a desktop application used to efficiently conduct structural fatigue analysis.

Fatigue Essentials provides a user friendly tool for conducting Stress-Life analysis either using classical stress calculations or linked with FEMAP™ and using the finite element generated stresses. The program is structured to guide the user through the analysis by following a tree structure.

General analysis options are selected following loads, materials, and spectrum branches. Within each branch are options for analysis variations or input methods. Analysis results are available on screen to paste into a report and/or as a damage contour plot in FEMAP.
