EEEN20021 - Materials and Structures
Availability - Course (Compulsory/Elective)
- Introduce the fundamental mechanical characteristics of materials.
- Introduce the techniques used to calculate strain and stress in structures.
This unit will cover the following:
Introduction to Materials
Review of physical concepts; structure of materials and influence on properties; relative costs of materials; information sources for properties and size standardisation.
Mechanics of Materials
Review of terminology and concepts; stress, strain, elasticity, yield and strength; ultimate stress; Hooke's Law, Young's Modulus, Poisson's Ratio; tension, compression, shear; thermal stress; strain energy; torsion in shafts; deflection of beams; shear, bending moment; stress transformations: Mohr's Circle; buckling; forces in and analysis of structures. Failure of materials. Stress concentration; toughness; fatigue failures.
Students will be able to:
Knowledge and Understanding:
- Identify the influence of material properties on strength
- Understand the concepts of stress, strain and elasticity
- Understand the concepts underlying tensile , shear, torsion and bending effects
- Analyse a mechanical system with respect to moment and force equilibrium
- Select materials for engineering applications
- Develop skill in operation of mechanical testing equipment for deflection of materials (bending and torsion)
Transferable skills and personal qualities:
- Develop transferable skills in presentation of material
