Reliability Toolkit

Coffin-Manson Thermal Cycling Acceleration Factor Calculator

Compare cycle severity using a simplified Coffin–Manson relationship based on temperature excursion and a user-selected fatigue exponent.

Engineering inputs

Temperature excursion in the specified in-service or mission environment. Supported range: 1e-06 to 600.

Supported range: 1e-06 to 600.

Supported range: 0.01 to 20.

Supported range: 0 to 1e+09.

Results

Your calculation

Enter the inputs and select Calculate.

Model notes

Excursion-only fatigue model with the same mechanism at Field and Test conditions. Acceleration is cycle-based; dwell, ramp rate, maximum temperature and cycling frequency effects are excluded.
