Intended learning outcomes

The course aims to give the student theoretical and practical knowledge of composite materials. The main part of the course deals with theoretical principles which are then put into practice in homework, a design assignment and a computer exercise.

After the course the student is expected to

  • Explain the mechanical behaviour of anisotropic materials and how they differ from classical construction materials
  • Apply classical lamination theory to analyse the stiffness and strength of composite laminates
  • Design a composite laminate with given requirements
  • Be able to make calculations and estimates on the stiffness and strength of composite plates
  • Be familiar with methods for more advanced tools of composites analysis and design including failure theories and their implementation, the effect of holes and cracks, fatigue, and models for the prediction of compressive failure mechanisms
  • Describe potential problems and ways to analyse composite structures with FEM
  • To formulate and solve a composites design problem and communicate the results in a written report.

Course main content

Micromechanics, classical lamination theory, failure criteria including problem solving and a programming assignment based on these theories. The course continues with anisotropic plates, advanced methods for fatigue and fracture analysis and an overview of testing methods. Finite element modelling of composites is also covered. Compulsory elements of the course include, besides a written exam, a programming and design problem.

Eligibility

Base programme B, M, T. SD2411 Lightweight Structures and FEM and SD2414 Fibre composites - Materials and manufacturing are strongly recommended. Some experience with MatLab or programming in some other computer language is recommended.
