What This Fatigue Damage Calculator Can Analyze
This fatigue tool is built for real engineering workloads — where metal, steel, composite or rotating components experience thousands or millions of stress cycles. It converts your CSV stress data into fatigue damage, life estimation and graphical analysis.
Industries That Use Fatigue Analysis
- Aerospace — wings, fuselage skins, turbine blades
- Wind Turbines — blade fatigue, hub stress cycles, tower vibration
- Automotive — suspension arms, axles, connecting rods, chassis
- Mechanical Engineering — rotating shafts, gears, bearings
- Industrial Machinery — press machines, load-bearing arms
- Robotics — repeated motion joints and actuators
- Construction — structural beams, welded joints under vibration
- Marine & Offshore — ship components under wave loads
Who Can Use This Tool?
- Mechanical engineers
- R&D laboratories
- Universities and students working on fatigue projects
- Automotive designers & CAE engineers
- Wind turbine maintenance teams
- Structural engineers
- Industrial machine designers
- Failure analysis teams (FEM & forensic engineering)
CSV File Format (Very Important)
Your CSV file must contain ONLY stress values, one per line. No headers, no commas. Just pure numbers.
