Eligibility
General entry requirements for bachelor's level (first cycle)Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.
Specific entry requirements
The same as for the programme that owns the course.Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.
Course specific prerequisites
The courses LMA401 Calculus, MVE580 Linear algebra and differential equations, LMT202 Mechanics, TME255 Strength of materials, MVE645 Programming and numerical methods using Python and LMA017 Mathematical analysis in several variables, or corresponding knowledge.Aim
The course gives you important skills to evaluate stresses and deformations along with failure assessments of various 2D components. Also, ways to assess the stability of the components are developed. Emphasis is placed on the modeling of multiaxial stress and strain states in elastic 2D structures. 2D structures are elastic plane strain, plane stress and axisymmetric components. In this context, structural modeling of plates and technical shells is also developed. Models for material failure are developed based on the stress analysis. Another emphasis is on the concept of structural stability for defining limit loads of beam structures.Learning outcomes (after completion of the course the student should be able to)
- formulate the concepts of multiaxial stress and strain;
- determine the principal stresses and principal stress directions;
- formulate and analyze isotropic thermoelasticity;
- describe and analyze plane stress, plane strain and axisymmetry;
- formulate the concept of structural stability;
- solve simplified problems of structural stability;
- analyze stresses and deformations of 2D solids, plates and simplified shells;
- explain the stress distribution around concentrated loads;
- describe and analyze stress concentration factors.

Literature
Communicated at the course home page.Examination including compulsory elements
The course is assessed through a project and a final exam. The project yields credit points to the exam. An approved course requires also two approved on-line quizzes. Grading scale TH (fail, 3, 4, 5).The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
