Advanced Training Structural Dynamics

...a fascinating engineering topic which requires sound knowledge!

Description

Structural dynamics is a fascinating but complex topic, which requires good understanding of the theoretical background and its application in the Software. This training will guide you through the fundamentals of structural dynamics and demonstrates the application in FEMAP with Simcenter Nastran based on examples.
