Easily calculate damage and safety factor for simple stress distributions, even with assembly preload and temperature dependency. Example applications: bulkhead ignition, cavity pressure.

FEMFAT Channel Max

Combine unlimited channels of load histories into a single complex fatigue calculation. Example applications: subframe vibration, pothole impact

FEMFAT Trans Max

Sequence transient stress distributions and predict fatigue life of load cycles. Example application: bearing wall with rotating loads, braking loads.

FEMFAT Spectral

Study multiaxial stochastic loading exclusively in the frequency domain with power spectral densities (PSDs) for increased efficiency at no cost to accuracy. Example application: road load durability of mounting brackets.


Use transient stress, strain, and temperature data to compute mechanical, oxidation, and creep damage with FEMFAT’s special TMF material and damage models.


Powerful weld fatigue analysis featuring an easy-to-use 3D weld definition in FEMFAT Viewer. Study weld joint, shape, materials, and even sensitivity to manufacturing variation.

Material Generator & Database

Access FEMFAT’s extensive material library or generate your own material models from your own parameters with ease.

Designed and Tested for Your Needs

FEMFAT is compatible with your solver of choice and will integrate seamlessly into your existing workflow.

Flexible Post-Processing

View results in 3D and probe them in detail with FEMFAT Viewer, or export to the post-processor format of your choosing.

Optimization Software-Compatible

Optimize your design for fatigue damage by pairing FEMFAT with an optimization code such as Tosca Structure.
