Most simulation users employ FEA to predict breakage as defined by the stress-strain material curve. However, in reality, most part failure is due to fatigue damage accumulated over time, and this can be predicted.

FEMFAT is universally applicable software for fatigue analysis of statically and/or dynamically loaded components and assemblies.  Based on stresses from FEA, FEMFAT delivers analysis results such as fatigue life or damage, as well as safety factors.  This enables the identification of structural weak spots and lightweighting design opportunities at an early product development phase.
