Understanding and Applying Structural Dynamics (FutureLearn)

In this course you will learn the fundamentals of dynamics. And explore dynamics is relevant to structural engineering. By the end of the course you will have a new perspective on the qualification and behaviour of all mechanical systems.

What topics will you cover?

This course sums up the foundation of solid dynamics applied to structural analysis, as follows:

- A first item deals with the fundamental signification of dynamics. Dynamics is not simply an extension of statics, but another modeling with open possibilities (including statics, obviously). The basic theorems (Newton’s equivalence principle, König’s theorems, conservations) are detailed in the perspective of structural applications.

- The second point presents the generation of discrete dynamic systems, in the general formalism of Lagrange, well adapted for numerical modeling of dynamics. This toll is essential for the general representation of dynamic systems.

- Then the third step consists in the generation and solution of matrix equations in the frame of conservative structural systems, with Gaussian modes. This part is important for the comprehension of the eigenshapes in vibration and shocks.

- In the frame of the theory of prismatic beams, the application of the general dynamic formalism to continuous thin elementary is an example of generalization of the eigenshape theory and general dynamic representation of structures.

- The four parts can be studied sequentially or independently; and even inside each part, elementary learning items can be picked up.

What will you achieve?

By the end of the course, you'll be able to...

- Recognise dynamics problem and select the possible model category

- Identify, classify and discuss the general dynamics equations of Lagrangian systems

- Apply and use the dynamics equations and solutions of beam systems

- Analyze and distinguish fundamental problems considering discrete systems (masses, inertias, eigenshapes)
