nCode DesignLife: Fatigue Analysis of Welded Structures

Learn how to predict the fatigue life of welded structures using nCode DesignLife with instructor-led training.

Welding is a commonly used and effective method of joining materials such as metals. However, the nature of the welding process means that the welds generally have a fatigue strength that is inferior to the parent metal. This instructor-led online course investigates fatigue life prediction methods specific to welded structures. nCode DesignLife: Fatigue Analysis of Welded Structures builds upon our introductory course, nCode DesignLife: Fatigue Analysis using FEA Results. It provides an in-depth view of weld fatigue prediction, including analysis methods for spot and seam welds. An emphasis is placed on hands-on comparisons of different weld fatigue analysis techniques so you'll learn best engineering practices while gaining software proficiency.

Online courses are delivered in real-time with a live instructor.

Learning objectives

  • Import geometry and stresses into DesignLife from all major finite element (FE) software like ANSYS, ABAQUS, NASTRAN, LS-Dyna, Altair OptiStruct, etc.
  • Recognize the role of welding in fatigue.
  • Compare and contrast methods for fatigue life prediction methods for welds.
  • Create analysis processes for spot and seam welds.

Topics included

  • Introduction to fatigue of welds
  • Analysis approaches for weld fatigue life prediction
  • Structural stresses from FEA modelling
  • Spot weld method
  • Standards-based weld classification methods
  • Volvo seam weld method
  • WholeLife seam weld method for total life prediction
  • Tips and tricks for software proficiency

Course length

Online: 2, 3-hour sessions

Onsite: 1 day

Target group

This advanced course is aimed at engineers who have completed nCode DesignLife: Fatigue Analysis using FEA Results and would like to take a more in-depth look into predicting fatigue life on products that are welded. It is assumed that attendees have familiarity with FE modeling practices and general structural analysis concepts.


This course requires the use of a computer with a licensed nCode software installation. All registrants will receive a temporary nCode software license. Online courses also require an audio device with a microphone or a telephone. Dual monitors are recommended. The instructor will make use of a webcam. Webcams for attendees are optional but encouraged.

Prerequisite: nCode DesignLife: Fatigue Analysis using FEA Results or equivalent knowledge and experience.
