Advanced Dynamic FEA

This course covers a broad range of solution types, beyond the usual natural frequency and dynamic response methods. This allows more physical phenomena to be investigated and simulated using dynamics in FEA.

Topics covered include; Random Vibration, Shock and Response Spectra, Nonlinear Dynamic Response, Explicit Dynamic Analysis and Complex Eigenvalue Analysis.

What will you learn?

• The theory behind advanced dynamic analysis techniques
• A practical understanding of advanced applications
• Hints and tips for setting up advanced dynamic analyses
• A roadmap for understanding the results from dynamic analysis
• The limitations of simulation methods

Who should attend?

• Designers and engineers who are familiar with dynamic analysis and want to learn more
• Experienced engineers who want to brush up on their advanced dynamic analysis knowledge

The course is completely code independent.

This is a 4-session online training course, with each session lasting for approximately 2/2.5 hours, depending on homework submissions, questions & discussions.

You can attend the sessions live, and/or stream on demand. When you register you will get access to a dedicated course forum where you can contact the tutor with questions, submit homework, download pdfs of course notes and access all session recordings. To get the most out of the course, participation in forum discussions is encouraged.
