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 course LMT207 Mechanics, or equivalent knowledge.

Aim

The course shall give a first introduction to the basic definitions and an introduction to the most common metallic engineering materials and polymeric materials. One base in the course is the connection between microstructure and the mechanical properties. The course shall also give a comprehension over properties and how they can be altered with heat treatments and other thermomechanical treatments.

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

  • account for how static mechanical properties are preformed and evaluated.
  • how the quantity ductile/brittle is tested and evaluated (impact test, fracture mechanic tests).
  • explain how fatigue tests are done (high cycle fatigue, low cycle fatigue and crack propagation).
  • account for the properties that can be evaluated from a different fatigue tests.
  • apply these fatigue properties on a mechanical design.
  • account for the most common metallic and polymeric engineering materials.
  • explain the mechanical properties can be related to the microstructure.
  • explain how properties in a material can be changed by manipulation of the microstructure.
  • execute an elementary materials selection.
  • use the database "eco-audit" to understand a designs environmental.

Content

This course deals the most common metallic and polymeric engineering materials. Requirements put by a mechanical design simple materials selection philosophies will be discussed. As an aid in this part of the course a materials data base will be at the students disposal to select both materials and manufacturing processes. The basic properties of the materials are defined and techniques for their evaluation are discussed and practised. Examples of properties are the static strength of materials (Yougs modulus, yield strength, tensile strength and fracture elongation) that are evaluated from a stress-strain curve. Importance of ductility and brittleness are elucidated when impact tests and fracture mechanic tests are introduced. Fatigue of materials is another important concept here the load of the component varies with time. Different test methods, high cycle fatigue, low cycle fatigue and crack propagation are defined. Focus will be on high cycle fatigue (Whöler curves) and the connection to crack propagation. Test strategies and evaluation techniques are defined for the latter methodes. The mechanical properties are determined by the microstructure in the materials, this is discussed at the end of the course. How microstructure can be manipulated with heat treatments and other thermomechanical treatments are discussed. At the end of the course environment and sustainable developments of the materials are treated (1 P).

Organisation

The course is divided in three theoretical modules and one applied as follows: Module 1: Basic material properties, how they are structured to be searchable, material selection work order from product requirements, derivation of material indices for stiffness. Module 2: Manipulation of mechanical properties, e.g. hardening using heat treatment and reinforcement using fibres. Module 3: Plastic deformation and strength, derivation of material indices for strength, mechanical failure mechanisms, e.g. fracture mechanics and fatigue Modul 4: Complementing assignments for each module 1-3, respectively.

Examination including compulsory elements

Course examination contains quizzes per module, respectively, each passed individual, which add to the final grade, where grade 3-5 is pass, beside compulsory group assignments.

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.
