Prerequisites A basic course in mechanics of composite materials.
The basics of anisotropic elasticity and composite materials will be reviewed
at the beginning. If you have not
taken a course in composite materials, but if you are still interested in the
topics below, contact the instructor for further discussion.
Goals The major goal is to teach
advanced analysis methods for composite structures.
Applications Currently fiber reinforced and particle
reinforced composites are used in aerospace, automobile, marine and rail transport,
electronic packaging, buildings and bridges (civil infrastructure), sporting
goods etc. Further, active materials such as piezoelectric materials, have
potential for use in aerospace structures, and civil infrastructures such as
bridges and buildings. This course will help engineers to design these
structures based on sound mechanics principles.
Topics 1. Introduction and review of basic principles
2. Analysis of laminated anisotropic plates:
2a) Plate equations of motion
2b) Energy formulation
2c) Static analysis of laminated
plates
2d) Free
vibration and dynamic analysis
2e) Stability of laminated plates
2f) Shear deformation
2g) Large deflection
of laminated plates
3. Sandwich construction
4. Advanced micro-mechanical methods for
(a) Thermal properties
(b) Mechanical properties
(c) Strength prediction
5.
Elements of fracture mechanics of composites
Analysis of delaminated plates
including buckling
6. Advanced Topics
(a) Functionally Graded Materials & Structures
(b) Mechanics of layered plates containing active materials
