What We Do
Fatigue Assessment
Fatigue assessment is used to understand how a component or structure responds to repeated or cyclic loading over time.
A component can withstand a single applied load without yielding and still eventually develop cracks or fail when subjected to repeated loading. Fatigue assessment helps determine whether a design has sufficient durability for its expected operating conditions.
QANTIS Engineering Group provides consultancy-grade Finite Element Analysis (FEA) and fatigue assessment to evaluate stress cycles, fatigue behaviour and potential service-life limitations.
Typical engineering questions include:
How long is the component expected to last under cyclic loading?
Where are fatigue-critical regions likely to occur?
Is the stress range acceptable for the required service life?
Could a change in geometry improve fatigue performance?
How do different loading conditions affect fatigue life?
Is the current design suitable for its expected operating cycles?
The objective is to understand how repeated loading affects the component over its service life and whether the design has sufficient durability.
Why This Analysis Matters
Fatigue failure can occur at stress levels well below the material's static strength. Local stress concentrations, repeated load cycles, surface features and changes in loading can all influence fatigue performance.
Fatigue assessment can help engineering teams:
Estimate fatigue life under defined cyclic loading conditions
Identify fatigue-critical locations before they become failures
Assess durability against required service life
Understand the effect of stress concentrations and geometric features
Compare design changes intended to improve fatigue performance
Support reliability and validation decisions for components subjected to repeated loading
Fatigue performance depends on more than the maximum stress. Stress range, mean stress, loading sequence, material behaviour, geometry and the required number of cycles can all influence the result.
The important question is not simply whether the component is strong enough today, but whether it can withstand the loading it will experience throughout its intended life.
