  • First semester 2017 (Day)


Specific modulus and specific strength; 3D stress and 3D strain tensors; anisotropic elasticity; composite lamina and composite laminate; hygrothermal strain and hygrothermal stress analysis of composite structures; failure theories for a composite lamina; micromechanical analysis of a composite lamina; classical lamination theory for composite laminate, failure analysis of composite laminates, design of composite laminates, finite element analysis of composite materials and structures.


At the successful completion of this unit you will be able to:

  1. Describe the application of composite materials in modern industries and explain the advantages of applying composite materials in structures.
  2. Identify the stress-strain relationships for anisotropic materials.
  3. Analyse the strength and stiffness of composite laminate structures.
  4. Design composite laminates to meet strength, stiffness and cost requirements.
  5. Generate finite element analysis on anisotropic materials and composite laminate structures.
