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

 

Computer        Some numerical work necessary; MATLAB or other high level language on PC should be sufficient.
