Finite Element Method, Advanced

Code

ME-FEM2

Version

1.2

Offered by

Mechanical Engineering

ECTS

Prerequisites

Knowledge about distribution of stresses and strains in solids as well as confidence performing calculations with matrices is required. Furthermore, good knowledge about the general finite element method is required. These topics are covered in the VIA courses ME/MA-MEC2, ME/MA-MAT2, and ME/MA-FEM1

Main purpose

The main purpose of the course is to enable the student to solve nonlinear static problems and dynamic problems using the FE method and to give the student an overview of how a thermal analysis is performed using the FE method.

Knowledge

The student will gain knowledge about the FE method and its applications, including:

Static stress analysis using FE
Element types
Validation of the FE model
Error estimation
Adaptive mesh generation
Linearized buckling analysis
Free vibration analysis
Structural dynamic problems
Nonlinear solution methods
Large deformations analysis
Nonlinear material modelling and analysis
Contact analysis
Problem solving with Ansys Workbench
Introduction to Ansys Classic
Introduction to heat transfer and coupled problems

Skills

The student will be able to:

Solve linear static problems using Ansys APDL
Perform dynamic FE calculations using Ansys Workbench and Ansys APDL
Interpret the results from a dynamic analysis and understand what they imply
Accommodate the FE method to deal with different types of nonlinearities
Perform nonlinear FE calculations using Ansys Workbench and Ansys APDL
Validate the results obtained from Ansys Workbench and Ansys APDL

Competences

Upon taking the course, the student will be able to judge about the possibilities in using commercial FE soft-ware in dynamic problems and in nonlinear static problems. The student will be able to validate his / her FEM models.

Topics

Teaching methods and study activities

The teacher will go over the course topics in the classroom, combining theory with exercises and blackboard teaching with PowerPoint presentations.

The student is expected to read the detailed literature and to solve compulsory assignments between les-sons.

3 lessons per week for 12 weeks. The workload for student is expected to be 138 hours.

Evaluation

Examination

Requirements for attending examination:
The course assignment must be handed in before the set deadline. Fail to meet the prerequisites will disqualify entering the examination. As of re-exam, a new set of assignment(s) and deadline will be set before the re-exam.

Type of examination:
Individual oral examination based upon a subject found by draw. Examination accounts for 100% of the final grade
Duration: 20 minutes
A laptop with Ansys installed is needed at the oral examination
Censor: Internal

Allowed tools:
None

Re-examination:
As ordinary
