fe-safe is the technical leader in fatigue analysis software for Finite Element models. It was the first commercial code to implement modern multi-axial strain based fatigue methods, going beyond the capabilities of peak-stress based methods to determine damage through critical plane searching; allowing the directionality and order of load sequencing to be considered.
Critical plane searching to find most damaged plane
It is code-independent, so that it can be readily coupled with leading FE-solvers, or work with an open format of element stress and material data.
Data flow to fe-safe
Through a powerful load-history approach, detailed material data and multiple damage prediction methods fe-safe can be used for a complete durability by design approach that allows you to accurately predict fatigue life of your components.
Critical plane searching shows shortest life is NOT always coincident with max principal stress location
Control of load history allows prediction of accurate failure modes based on sequence of part damage
