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 LMT202 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)

  • develop a basic language about materials and their use throughout the life cycle
  • understand and evaluate a material¿s most important mechanical properties
  • explain the relationship between microstructure and mechanical properties.
  • explain how the mechanical properties can or cannot be manipulated.
  • explain how the mechanical properties of a material can be used in mechanical design.
  • describe the differences between different classes of materials and their use including metal, polymer, ceramic, glass, rubber and hybrids.
  • perform simpler material selection analyzes.
  • explain in detail different types of fatigue.
  • describe how a choice of material is made from a requirements profile including several perspectives such as function, form, manufacture and sustainability.

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 thermo mechanical treatments are discussed.

At the end of the course environment and sustainable developments of the materials are treated (1 credit).

Organisation

The course prosecutes conventionally with lectures, exercises, lab work and individual studying (ca 100 h). The lab work deal with the most central concepts in the course (1,5 credits).

Literature

M. Ashby, H. Sherecliff, D. Cebon: Materials engineering, science, processing and design 2 ed. Literature in the more advanced fatigue part will be defined at the start of the course.

Examination including compulsory elements

Examination is done with a conventional written test. Approved grades are 3, 4 and 5. Lab work is compulsory (1,5 credits).
