Products exposed to cyclic loads rarely fail on day one. They fail after months or years, when small cracks have grown and damage has accumulated in welds, bolts, and load-carrying components. Predicting fatigue life is difficult early in development. Loads vary with usage, environments can be harsh, and local stress concentrations are easy to miss until testing or field operation reveals a weak point.

Fatigue failures are expensive to fix once the product is in the field. They can lead to unplanned downtime, warranty costs, redesign work, and loss of confidence in the product. Fatigue and lifetime engineering helps you address these risks early, while design changes are still fast and cost-effective.

By combining practical product development experience with advanced analysis, we help you assess failure modes, verify critical connections, and design for the expected lifetime under real operating conditions.

Our Fatigue and lifetime services include:

• Fatigue analysis and fatigue load processing for realistic duty cycles.
• Weld and bolt verification to reduce size and weight while maintaining safety margins.
• Fracture mechanics, including brittle fracture risk in steel for cold climates.
• Vortex-induced vibration fatigue assessment and stress concentration factor (SCF) extrapolation.
• Reliability engineering, RAM analysis, and lifetime engineering to support availability targets.
• Robust design, DFMEA, and PFMEA to identify and mitigate failure drivers early.
• Verification to relevant industry standards such as IEC 61400, DNV, and ASTM F24.

We use proven toolchains such as ANSYS Mechanical and APDL, automated fatigue tools in Python and Mathcad, and VDA coding practices to support traceable and repeatable verification.

With fatigue and lifetime performance verified early, your product development can move forward with confidence. Together, we help you deliver products that reach their expected lifetime, enable lighter and more cost-efficient connections, and reduce failures and downtime in operation.
