Computer-Aided Analysis of Mechanical Systems

Base Knowledge

Applied Mechanics. Strength of Materials. Structural Mechanics. 3D Modelling.

Teaching Methodologies

In the theoretical component of the course, the expository method will be used. Following the acquisition of theoretical knowledge, application examples will be executed, favoring the exchange of ideas, approach and problem solving by the students themselves during the class. Both cases will be supported by the visualization / use of the computer program Solidworks, version 2021.

The final agglutinating work intends to deepen skills in the application of the concepts described, as well as to consolidate skills in the execution of a technical report, presentation and discussion of it.

Learning Results

This Curricular Unit consists of a theoretical learning component and a vital laboratory development and application component. It is intended that students acquire knowledge and skills to understand the numerical approach to problems of calculating mechanical components and systems based on the finite element method. At the end of the course, the student should be able to correctly prepare a finite element model and interpret and evaluate the quality and reliability of the results.
