Entry requirements

60 credits in science/engineering including Materials chemistry.

Learning outcomes

After passing the course, the student must be able to:

• explain the atomic background to the modulus of elasticity and the influence of dislocations on plastic properties,
• explain the role of dislocations for different hardening mechanisms and calculate how their contribution to hardening,
• explain and categorize mechanisms of deformation, failure and fatigue in metallic, polymeric and ceramic materials,
• explain the influence of deformation rate and temperature on mechanical properties of polymeric and metallic materials,
• explain and calculate the effect of fiber reinforcement in metallic, polymeric and ceramic materials,
• describe and use the most common test methods for mechanical materials properties.

Content

In-depth comparisons between the different material classes; metallic, ceramic and polymeric materials as well as various types of composites. Relationship between the internal structure of the materials, from the nano level to the macro level, and the mechanical properties. Kinetics and dynamics of dislocations, elastic and plastic deformation, hardening mechanisms, crack initiation, fracture mechanics, fatigue and creep. Laboratory work containing extensive testing of various mechanical properties are included as important elements in the course.

Instruction

Lectures, problem-solving sessions, study visits and laboratory work.

Assessment

Written exam (4 credits). Laboratory work (1 credit).

Other directives
