The purpose of this course is to describe simple methods for multibody kinematic and dynamic simulations, and basic study of finite element methods. This feature is being used more and more by the engineering profession for analysis and design. The goal of this course is to demonstrate how such methods work and how they interact with models.

To obtain a passing grade the student must be able to: independently perform planar and simple 3D models for mutibody analysis,

develop a planar FE model of truss structures,

evaluate both accuracy and relevance of numerical results and write a short report on the features of numerical models and results interpretation.
