Damage Modeling

Abstract

What exactly is “damage” in engineering, and how do you predict when it will end a product’s life? Join Mojan and Fred as they explore damage modeling through the lens of reliability engineering. They discuss why understanding damage accumulation is critical for both designers and field teams, and how monitoring thresholds throughout a product’s life can transform maintenance and testing strategy.

Key Points

Join Mojan and Fred as they dive into the mechanics of damage and why modeling it is essential to reliable design:

Topics include:

What is damage? From corrosion on steel to microscopic fatigue cracks, damage is measurable and predictable when you understand the underlying physics
Miner’s Rule: the most widely used approach for modeling how damage accumulates across repeated cycles and loading events
Why bigger stress changes in a cycle “cost” more life—and how to quantify that trade-off mathematically
Moving beyond worst-case assumptions: using damage models to set realistic detection thresholds and monitoring intervals
How monitoring actual damage accumulation throughout a product’s life enables faster, more efficient testing and smarter maintenance decisions
The critical link between damage modeling and usage percentile: understanding real-world deployment patterns to validate field performance
