2025 Global FEA NX Webinar Series 1 Steel Structure Fatigue Analysis under Repeated Loads August 11th, 2025 - 09:00 CEST / 15:00 SGT / 17:00 AEST

The first session focuses on Fatigue Analysis of Steel Structures under Repeated Loads, structured to be easy to follow even for non-experts. Understand the fatigue damage mechanisms of steel structures under repeated loads and explore how to conduct fatigue life assessments using 3D FEM with FEA NX. This session introduces S-N and E-N based methods applied to bridge structures, with step-by-step learning. 

 

 

🛠 Key Civil NX Features Covered

  • Definition and causes of fatigue

  • Fatigue life estimation theories based on S-N / E-N methods

  • Overview of fatigue analysis workflow using FEA NX

  • Application of fatigue prediction models such as Goodman, Morrow, SWT

  • Practical examples for predicting fatigue life of steel members 

     

     

 

🎯 3 Takeaways for Attendees

  1. Learn fatigue analysis theory and practical application using S-N and E-N methods 
  2. Understand FEA NX’s multiaxial stress transformation and life prediction capabilities 
  3. Gain insights for improving bridge design based on fatigue analysis

Q&A Highlights

Q. How to import a file from Midas Civil NX to FEA NX

A. We can export a file from Civil NX by using the option called " Frame Section for Solid". Then we can import this file into Fea NX by using the option called "Frame to solid".

Q. How to simulate welding in FEA NX

A. We can set the contact parameters as per our requirement to simulate the welding. Refer to the following tutorial.
