Eligibility:


In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

Mathematics courses in linear algebra and calculus in several dimensions.

Aim

The aim of the course is to provide the basis of the finite element method (FEM) and its use for deformation, stress and strain analysis in mechanical system design

Learning outcomes (after completion of the course the student should be able to)

  • Describe the theoretical basis for the finite element method (FEM), applied to linear elastic problems.

  • Describe the practical steps, necessary to create an FE-model in a commercial software.

  • Create a complete FE-model from aCAD-data in a commercial software.

  • Use commercial software to
    - compute stresses and deformations in a structure.
    - design a component based on usage limit conditions.
    - design a component based on limit load conditions.

  • Describe the concept of convergence of an FE-solution and describe the rate of convergence and how this is affected by different element approximations as well as geometry.

  • Identify situations which will lead to stress singularities and stress concentrations and how to account for this.

  • Create and modify an FE-discretization to reduce the discretization error

  • Apply St. Venant's principle to evaluate the effects of boundary conditions.

  • Choose elements suitable for analyzing a given structure.

  • Model structures with elements of the type: springs, bars, beams, plates, shells, and solids.

  • Discuss different sources of error and gives examples, when a physical problem is described using a structural model.

  • Judge the validity of an FE-solution.

Content

  • Basics of the FEM with focus on linear elasticity problems.

  • Basics of constructing elements: numerical approximations and geometric approximations.

  • The assembly process for constructing the stiffness matrix and load vector, solution of linear systems of equations,calculating stresses.

  • Identifying and handling of different boundary conditions.

  • Create and analyze FE-models in commercial software.

  • Interpret and evaluate FE-results.

Organisation

The course contains about 30 h of lectures and about 30 h of computer lab. The lectures cover the theory which is also exemplifed by calculations. During the computer labs, students work on hand-in assignments under teacher supervision.

Literature

Will be notified prior to the course starts.

Examination including compulsory elements

A written exam which determines the grade. To pass the course, all the computer assignments need to be approved.
