Aims

Learning outcomes and training goals

  • K2L To possess basic scientific and disciplinary knowledge and understanding in one of the fields based on the chosen specialisation
  • I1L Analysing and solving problems
  • I2L Designing and/or developing
  • I2V Adopt a creative and innovative attitude
  • I3L Application-oriented research
  • G1L Acquiring and processing information
  • G3L Reflecting critically

Objectives

  • The student has a deeper knowledge of the subjects from the theory of strengths relevant to mechanical engineering with an emphasis on their technological application.
  • The student is able to schematize to a mathematical calculation model, to justify the choices made (also in case of irrelevant and/or incomplete data), and to critically evaluate the calculated results on correctness and relevance. 
  • The student is able to calculate or design constructions, taking into account the boundary conditions (e.g. permissible material properties and deformations, nature and method of loading).
  • The student is able to determine the deformations and stresses of solid or thin-walled cross-sections for (a combination of) the four elementary cutting forces (normal force, bending force, transverse force, torsion).
  • The student is able to study the complete stress state in a point including thermomechanical stresses.
  • The student is able to analyse the buckling of a machine part.
  • The student must be able to describe the concepts of Finite Elements, degrees of freedom, convergence, load, boundary conditions, nodes, elements and mesh for the mechanical and thermal fields.
  • The student must know how to use an FEM package as a design tool in order to achieve the best possible design. The emphasis is on the correct input of known data and a critical interpretation of the results.
  • The student must be able to form a well-founded opinion about the quality of a finite element analysis and the results that come from it.

1.5 ECTSEnglishFormat: Lecture12 First term
De Roeck Wim
OC Elektromechanica - Campus Groep T Leuven

Content

In this course the Finite Element Method (FEM) will be discussed for its general engineering applications, with specific focus on its applicability for structural and thermal applications.

The outline of this course is the following
•General introduction to FEM based methods with specific focus on the basic assumptions, advantages and limitations of FEM-based methods in general, and a comparisson with other deterministic modelling techniques.
•Domain discretization, with specific focus on the various 1D, 2D, 3D element types (1st order/high-order) and its influence on the final accuracy and computational (bot CPU-time and memory requirements) efforts.
•Model simplifications and its consequences based on engineering knowledge (i.e. using symmetry planes/axi-symmetric analysis/simplified material properties/...)
•Applications of FEM based numerical techniques.
•Introduction to the basic mathematical principles of FEM-based methods (with specific focus on structural mechanics)
•Definition of proper boundary conditions/constraints/loading terms (with specific focus on structural mechanics)
•Post-processing of FEM-results, i.e. validation of the outcome of a FEM analysis
•How properly reporting FEM-results?

Following applications will be used througout this course
•Application of FEM based methodologies to basics structural mechanics including 1D, 2D and 3D structures
•Advanced FEM modelling techniques for the structural mechanics modelling of surface-to-surface contacts/connections
•Application of FEM based methodologies to model heat transfer
 

Numerical exercises with commericel FEM-software (Siemens NX) will run parallel to the lectures.

OC Elektromechanica - Campus Groep T Leuven

Content

In the exercises of finite element based design, students will get acquantained with a proper use of commercial FEM software (i.e. Siemens NX) to calculate deformations, stresses, heat loads...

The purpose is to offer a general basic knowledge, representative for any type of FEM-software, on
•how to model (preprocessing) a specific problem in an efficient but accurate manner, i.e. choosing the proper element types/geometrical simplifications/boundary conditions/loading conditions
•the analysis and validation of FEM-results using the methods seen in the lectures of "applied strength of materials
•reporting 

The exercises consist of static structural mechanics problems. Specific focus is paid on where and how to apply loads and constraints, how the model can be simplified (1D,2D,3D modelling, mesh types,...) and on the critical interpretation of the FEM results.

Evaluation

Evaluation: Strength of Materials for Machine Design (B-KUL-T72268)

Type : Partial or continuous assessment with (final) exam during the examination period
Description of evaluation : Written, Report, Process evaluation
Type of questions : Open questions
Learning material : Calculator, Computer

Explanation


1. Calculation of the final mark

The final mark of this course is calculated based on the published component marks with the following weighting factors:

  • Component mark for lectures "Applied Strength of Materials" : 40%
  • Component mark for lectures "Finite element based Design" : 25%
  • Component mark for exercise sessions: 35%

 The mark for 'lectures' and 'exercise sessions' is a whole number out of 20.

The only exception to this rule is described in the complementary regulation of the Faculty of Engineering Technology to article 66 in the Regulations on Education and Examinations.

2. Calculation of the published component marks

The component mark for both ‘lectures’ is a whole number between 0 and 20, based on the exam.

The component mark for the exercise sessions is a whole number between 0 and 20. It is an evaluation of the student’s performance based on the evaluation of a test taken during the last session containing a computer assignment (carried out with SIEMENS NX)+ written report in combination with an permanent evaluation of the reports which are handed in during the academic year

3. Absences

Unauthorized absence during the exam leads to NA as a component mark for lectures.

Unauthorized absence during the test leads to NA as a component mark for exercise sessions.

For absences during the teaching weeks, please contact the education ombuds on the first day of your absence. If you missed one or more obligatory sessions, please contact your professor as soon as possible and certainly within a week. For absences within the exam period, please contact the exam ombuds on the first day of your absence.

When needed, additional information on the evaluation activities is provided during the lessons and/or made available on the toledo pages of the course. If the university decides that it is confronted with situations of general force majeure or situations where the safety and health of members of the academic community of KU Leuven may be endangered and changes to the teaching and evaluation activities occur as a result, these changes will be communicated via Toledo​

Information about retaking exams

This course unit allows partial mark transfers in case of partial pass mark:

  • T3hSM2 - Applied Strength of Materials (during and beyond academic year)
  • T3iSM2 - Finite Elements Based Design (during and beyond academic year)
  • T3oSM2 - Strength of Materials for Machine Design: Exercise Session (during and beyond academic year)

For the "lectures" part of both Applied Strength of Materials and Finite Element Based Design, the same modalities apply as for the first examination period.

For the part "exercises", a new test with NX is provided, the score obtained during this test fully replaces the previously obtained score of this OLA
