Interpolate cycles-to-failure from S-N curve using measured flex amplitude computes predicted cycles to failure in cycles and margin to fatigue limit in dimensionless (ratio) using the defined engineering formula and the input values provided. predicted cycles to failure is expressed in cycles; margin to fatigue limit is expressed in dimensionless (ratio). No universal acceptance threshold is defined by this calculator.
Worked Example
default_test
Given:
- duration = 1
- frequency = 1
Expected Result:
- margin to fatigue limit = 1
- predicted cycles to failure = 1
Engineering Interpretation:
Under the given input conditions, the calculated result is: margin to fatigue limit = 1 dimensionless (ratio); predicted cycles to failure = 1 cycles.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
predicted cycles to failure = duration*frequencypredicted cycles to failure; margin to fatigue limit.
