Available Modules

FEMFAT basic: Finite Element (FE)-based software for predicting the fatigue life/damage and endurance safety factors of components. Includes comprehensive FE-interfaces and material database.

FEMFAT basic is required to be open in order to use each add-on module listed below.

FEMFAT plast: A software module to consider the effects of redistribution of mean stresses when local plastic deformation occurs.

FEMFAT max: A software module for fatigue analysis of multiaxially loaded components using time histories of loads or series of stress states.

FEMFAT weld: A software module for fatigue analysis of welding seams for steel and aluminum using notch stress method and standards (DVS1608, EUROCODE 3 and 9, BS 7608, IIW).

FEMFAT spot: A software module for predicting fatigue of spot-joints (welds, rivets) in FE-shell structures.

FEMFAT break: A software module for assessing static safety factors.

FEMFAT strain: A software module for assessing damage from measured strains and comparing stresses from FEA and testing.

FEMFAT laminate: A software module for assessment of infinite fibre reinforced plastics respectively composites or laminates.

FEMFAT heat: A software module for the low cycle fatigue analysis of components that suffer from thermo-mechanical fatigue (e.g. cylinder heads, exhaust manifolds)

FEMFAT spectral: A software module to use Power Spectral Densities (PSD) for fatigue analysis in frequency domain for both Basic and Max analysis.

FEMFAT visualizer: A fast, 3D post processor to display the FE-model, fatigue results and imported stresses including stress animation.

FEMFAT parallel: Take the advantage to use more than only one CPU of your multicore workstation to speed up your analysis.

Modules and Products Not Currently Available Through the APA

FEMFAT LAB: Software for the administration of test rigs, analyzing time histories, identifying anomalies such as drift, mean shift and spikes that can be modified by a user; fatigue controlled mixture of track profiles generating equivalent damage; virtual iteration method in combination with MBS software.

DATACRYPT: This tool does binary encryption to material files and databases which can be then given to anyone outside the company- this person can perform the analysis with FEMFAT and this encrypted data, but any result or output (graph) where these data have been used cannot be displayed correctly- so that reengineering is not possible.

ELASTOLOADS: This tool is for long time signals where the engineer would like to do transient stress analysis and each stress result would be an input for FEMFAT, it is not only a burden for FEMFAT but also for the stress solver to provide thousands of stress results. So ELASTOLOADS automatically does a discretization of the load space in x, y and z directions and provides a perfect input for FEMFAT channelMax analysis where these thousands of stress results are replaced by at least 8 (2x2x2) results and a load history wherein a thousand steps the interpolation factors are combined. Hyperelastic material-like parts made from rubber such as engine brackets or bumpers in trucks can be analyzed or any nonlinearities like leaf springs.

HARMONIC: FEMFAT spectral requires stochastical and randomly distributed loading to convert such signals into frequency domain by Fourier transformations, the HARMONIC can calculate from deterministic signals like a linear or logarithmic sweep how many cycles at which amplitude the system will have to take and this can be prepared as an input for a channelMax analysis (in time domain) instead of a frequency based SPECTRAL analysis.

The tools ELASTOLOADS and HARMONIC are add-on tools for FEMFAT MAX provided by ECS with a separate license. Please request access with FEMFAT Support if you need these features.
