nCode DesignLife: Fatigue Analysis of Dynamic Structures

Learn how to perform vibration fatigue analysis on structures that experience dynamic stresses using nCode DesignLife with instructor-led training.

Resonance and dynamic effects can lead to large stress cycles that can be very damaging and reduce product life. This instructor-led online course investigates fatigue life prediction techniques specific to structures that experience dynamic stresses and explores methods that account for the critical interaction between dynamic excitation and structural response. nCode DesignLife: Fatigue Analysis of Dynamic Structures builds upon our introductory course to nCode DesignLife: Fatigue Analysis using FEA Results. It provides an in-depth view of vibration fatigue prediction, including analysis methods in both time and frequency domains. An emphasis is placed on hands-on comparisons of different dynamic 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 dynamic stresses into DesignLife from all major finite element (FE) software like ANSYS, ABAQUS, NASTRAN, LS-Dyna, Altair OptiStruct, etc.
• Recognize the role of vibration in fatigue.
• Compare and contrast between time domain and frequency domain approaches to fatigue analysis.
• Become proficient with time domain methods.
• Become proficient with frequency domain methods.
• Learn to replicate physical shaker tests on a virtual shaker table.
