Accelerated life testing workbench.
Choose a physical acceleration model, calculate the factor between use and test conditions, and translate target field exposure into an equivalent accelerated exposure.
Arrhenius acceleration factor
Translate thermally activated degradation between absolute temperatures.
Nonthermal stressInverse power law
Model life against voltage, load, pressure, vibration, or another consistent stress measure.
Combined stressTemperature-humidity acceleration
Combine an Arrhenius temperature term with a relative-humidity power term.
Thermal cyclingCoffin-Manson temperature range
Compare cyclic fatigue exposure using a reduced temperature-range model.
Mechanism first, factor second.
An acceleration factor is defensible only when the selected stress model represents the active failure mechanism and that mechanism does not change between use and accelerated conditions. Start with the model-selection guide, then use the formula reference to document symbols and limits.
These point calculations do not fit life distributions, estimate confidence bounds, set sample size, or prove a qualification requirement. Confirm material limits, competing mechanisms, stress interactions, and chamber capability before defining a test.
