nCode DesignLife: Fatigue Analysis using FEA Results

Learn how to perform CAE-based fatigue analysis with nCode DesignLife with instructor-led training.

nCode DesignLife: Fatigue Analysis using FEA Results provides an overview of fatigue life prediction techniques and offers instructor-led sessions where you will learn how to use nCode DesignLife software to perform fatigue analysis using stresses from computer aided engineering (CAE) tools. An emphasis is placed on hands-on comparisons of different 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.
• 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) time domain.
• 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.

Course length

Online: 4, 3-hour sessions

Onsite: 2 days

Target group

This 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 Practical Fatigue Theory course.

Requirements

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: None
