nCode DesignLife: Fatigue Analysis Using FEA Results

Learning objectives

• Import geometry and stresses into DesignLife from all major finite element (FE) software like ANSYS, ABAQUS, NASTRAN, LS-Dyna, Altair OptiStruct, etc.
• Define fatigue loading, from simple cycles to measured loading histories to vibration profiles
• Assign material fatigue properties
• Assess fatigue life with methods like stress-life (SN) and strain-life (EN) in both time and frequency domains
• Generate virtual stress and strain histories
• Apply stress superposition and multiple FE load cases
• Explore stress combination methods and plasticity corrections
• Identify and interpret fatigue hotspots
• Create reusable fatigue analysis templates

Who should attend

The course is aimed at engineers who need to predict fatigue life from FE-derived stresses. It is assumed that attendees are familiar with FE modeling practices and general structural analysis concepts. No prior working knowledge of nCode software is required. This course will briefly cover fatigue theory, but focuses more on using these concepts in software.

Attendees looking to learn more about the background of fatigue theory are encouraged to attend our 2-day course called Practical Fatigue Theory.
