DURABILITY FINFILYSIS SOFTWARE FOR FINITE ELEMENT MODELS

OVERVIEW fe-safe® is the technical leader in fatigue analysis software for Finite Element models. It offers its users the most accurate and advanced fatigue analysis technology for real-world industrial applications. fe-safe is used by leading companies in automotive, heavy truck, off-highway, marine, defense, offshore, power generation, wind energy, medical engineering and many other industries. fe-safe has been developed continuously since the early 1990's in collaboration with industry to ensure that it continues to set the benchmark for fatigue analysis software. fe-safe was the first commercially...

ANALYSIS METHODS fe-safe includes a wide range of analysis methods, all of which are included in the standard package: LOADINGS fe-safe can predict fatigue lives from a range of loading types: • Strain-based multiaxial fatigue algorithms—axial strain, shear strain, Brown-Miller with a multiaxial Neuber's rule and cyclic plasticity model • Single load time history applied to a linear elastic Finite Element model • S-N curve analysis including multiaxial fatigue using axial stress or a new Brown-Miller analysis formulated for use with S-N curves • Multiple time histories of loading superimposed...

Material database fe-safe outputs a wide range of results, in a single run: • Comprehensive material database of strain-life and S-N curve properties, fully validated and cross-referenced to international standards • Contours of fatigue life show crack initiation site • Contours of stress-based factors of strength for a specified design life—to show how much the stresses must be changed to prevent failure or to reduce material • Probability of survival for specified lives (the 'warranty curve') • Equivalent specifications allow searching on US, European, Japanese and Chinese standards • Users can...

How reliable is this design? fe-safe helps you answer these questions: What is the fatigue life of this component? fe-safe uses advanced critical plane multiaxial fatigue with in-built plasticity modelling to post-process results from an elastic FEA. Results can be displayed as contour plots showing crack locations and fatigue lives. Will cracks propagate? The 'warranty claim' calculation combines variability in material strength and variability in loading to estimate the proportion of components un-cracked after any period of time in service. This can be used to achieve uniform reliability over...
