70 IDE GK2 Material Technology

Prerequisites

Mandatory course for all students in first year.

Learning outcomes

Knowledge:
On completing the course the student should have acquired knowledge of various material properties such as . :
- The relationship between stress, strain and elasticity (E-modulus).
- Concepts such as yield strength, strength, elastic and plastic strain, ductile and brittle fracture etc.
- The material's mechanical properties (compressive and tensile, shear and bending, impact, ..)
- The materials' electrical resistance / conductivity
- Materials in different phases, melting point and boiling
- Materials heat capacity
- The materials' ability to isolate or conduct heat
- Thermal expansion
- density etc.

Students should also have acquired knowledge of some relevant material properties related to the following material groups :
- Metals (steel, aluminum, magnesium, ...)
- Natural materials (wood, cardboard, etc. )
- Mineral materials ( brick, concrete etc. )
- Artificial materials (plastics, composites, etc. )
- Smart materials, textiles

After completing the course the students will have learned how to choose the right material for the task based on :
- Function (may depend on various material parameters such as weight, conductivity etc. )
- Sustainability,
- Production,
- Price / economy,
- aesthetics
- durability
- formability
- Mechanical properties

Skills
On completing the course the student should be able to perform stress/strain experiments, calculate stress and strain based on forces and elongiation, as well as set up a stress-/strain curve where the elastic range, Young's modulus, yield strength, plastic range and ultimate stress are indicated.
Students will be able to do calculations on thermal conductivity, electrical resistivity and thermal expansion.
Students will also learn to recognize different types of wood.

Competences
On completing the course the student will have basic competency of materials and material parameters that are considered relevant to a study at AHO

Working and learning activities

Teaching at this course is based on lectures and exercises.
The course ends with an exam.
The lectures are divided into six different themes:
- Material properties
- Metals
- Natural materials (wood, cardboard, etc )
- Mineral materials ( brick, concrete , etc )
- Artificial materials ( plastics , composites, etc )

The exercises are partly theoretical partly practical .
A given number of exercises must be submitted and approved to take the exam.
Student assistants will be available for guidance.
The exam is a mix between multiple choice ( 70 % ) and a reasoning task (30 %).
