Durability Analysis Software for Finite Element Models
fe-safe
Industry is putting increasing pressure on manufacturers to use less material to deliver lightweight but stronger components, lower warranty and recall costs and all in less time.
Many companies use advanced Finite Element Analysis to calculate design stresses, but the fatigue analysis is often still done by manually picking stress points for spreadsheet analysis. This is time-consuming and unreliable because it is easy to miss failure locations.

Component validation by fatigue testing a prototype design in the test lab is time-consuming. If the prototype fails prematurely, a costly, open-ended cycle of design-test-redesign may be required. Project time-scales slip and delivery is late.
fe-safe, from the SIMULIA brand of Dassault Systèmes, is the world’s leading technology for durability analysis. Its capabilities have been developed to meet the most demanding industry applications. fe-safe is used by leading companies in the automotive, truck, off-highway, marine, military, off-shore, power generation, wind energy, medical engineering and many other industries.
fe-safe has been developed continuously since the early 1990s in collaboration with industry to ensure that it continues to set the benchmark for fatigue analysis software. fe-safe was the first commercially available fatigue analysis software to focus on modern multiaxial strain based fatigue methods.

WORKFLOW
LOADINGS
fe-safe can predict fatigue lives from a range of loading types:
- Single load time history applied to a linear elastic Finite Element model
- Multiple time histories of loading superimposed in fe-safe (more than 4000 load histories can be applied)
- Sequence of FEA stresses (elastic or elastic-plastic, linear or non-linear)
- Superimposition of steady state modal solutions
- Superimposition of transient dynamic modal solutions
- PSD loading, block loading test programs, rainflow cycle matrices
- Effects of forming or assembly stresses can be included
fe-safe includes a powerful, simple-to-use batch command system, with on-line parametric variation for ‘sensitivity’ studies.
