Cumulative Damage
Model Product Deterioration with Variable Stress over Time
Cumulative damage models, which include step-stress models, enable you to analyze an accelerated life test where the stress levels might be changed over time. The stress can be applied by many different forces: load, temperature, pressure. A typical cumulative damage experiment consists of multiple test units. Each unit has an initial stress level, and the stress level can be changed throughout the experiment. The response is the failure time or time-to-event. The platform plots the failure events and enables you to fit multiple distributions to your data.
