FEMFAT

Finite Element Method based Fatigue Analysis

Overview

FEMFAT performs fatigue analyses in combination with widely used fnite element programs. Interfaces to multibody, optimization and measurement systems ensure full and convenient integration into the customers’ CAE processes. FEMFAT provides engineers with reliable information on the fatigue life of structures to improve critical locations and/or reduce the total weight at an early stage of the design process, long before time-consuming and expensive tests are scheduled. This results in high quality prototypes and less testing effort.

FEMFAT is product of Magna Powertrain. DESIGNTEC as partner of Magna Powertrain promotes FEMFAT in Czechia and Slowakia.

FEMFAT Modules

Standard/Minimum configuration; includes all the interfaces and material database, handles 2 stress states plus one assembly loadcase for life- or safety factor analysis

Module to consider the effect of mean stress rearrangement from linear stresses when local plastic deformation occurs.

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

Module for predicting fatigue of spot-joints (welds, rivets) in FE-shell structures.

For low cycle fatigue analysis of components which are exposed to thermo mechanical loads (e.g. cylinder heads, exhaust manifolds) and suffer from mechanical, creep and oxidation damage.

Module for fatigue analysis of MultiAXially loaded components using time histories of loads or series of stress states.

A software module for assessing static safety factors in combination with BASIC or MAX.

Module for fatigue analysis of welding seams for steel and aluminum using notch stress method and standards (DIN 15018, EUROCODE 3 and 9, BS 7608, IIW).

A software module for fatigue life prediction on layered infinite fiber reinforced materials.

Fast 3D postprocessor to display FE-models, fatigue results and stresses including a feature to generate animations and to display 3D models in PowerPoint. Unmatched for weldseam definition.

Random response fatigue analysis using PSD (Power Spectral Densities) loads.
