Dynamics analysis by FEM technique (with application to ANSYS and examples): an introduction

Improve.it presents this distance learning short course aimed to introduce dynamics analysis by Finite Elements Method.
The multimedia material has a total duration of 2 hours and 20 minutes: 1 hour and 50 minutes are dedicated to the explanation of the basics, while 30 minutes are spent on simple practical examples of dynamics analysis using the ANSYS FEM code (the ANSYS classic interface).

Lecturer: Roberto Gonella, senior engineer and unit manager, EnginSoft SpA (Italy)
