Predict Product Lifespan and Prevent Unexpected Failures
A component that passes static strength testing today may still fail months or years later under normal operating conditions.
Repeated loads, vibrations, thermal cycles, and continuous operational stress gradually weaken materials over time. This phenomenon, known as fatigue, is one of the leading causes of structural failures across automotive, industrial equipment, heavy machinery, and consumer products.
At TAS US, our Fatigue Analysis Services help manufacturers identify potential failure points, predict component lifespan, and improve long-term durability before physical prototypes are built or products enter production.
By using advanced CAE fatigue simulation tools, we help engineering teams reduce risk, lower warranty costs, and deliver more reliable products to market.
What is Fatigue Analysis?
Fatigue Analysis is a simulation-driven engineering process used to evaluate how a component behaves under repeated loading cycles throughout its operational life.
Unlike traditional stress analysis, which determines whether a structure can withstand a single load event, fatigue analysis estimates how many load cycles a component can endure before fatigue cracks initiate and propagate.
Using advanced finite element analysis (FEA) and fatigue simulation software, TAS engineers replicate real-world operating conditions, including:
- Cyclic loading
- Mechanical vibration
- Road-induced impacts
- Thermal expansion and contraction
- Repetitive operational movements
- Variable amplitude loading
These simulations allow us to predict long-term durability without the cost and time associated with extensive physical testing.

Why Fatigue Analysis Matters
Many product failures are not caused by excessive loads.
Instead, they occur because relatively small loads are repeated thousands or millions of times.
Without fatigue analysis, engineering teams may face:
- Unexpected field failures
- Expensive warranty claims
- Product recalls
- Equipment downtime
- Safety risks
- Damage to brand reputation
By identifying durability risks during product development, manufacturers can avoid costly redesigns and improve overall product reliability.
