Course Outline

This course is designed to give the student an introduction to several advanced topics in the mechanical behavior of materials.  Emphasis will be given to understanding of the theoretical basis of each topic; however, advanced mathematical techniques will not be used.  Emphasis will also be given to theoretical, numerical and experimental modeling of the phenomena.  The course includes instruction in both the theory and use of finite element modeling.  The student will gain an overview of each topic, but also in-depth understanding of selected parts of each topic.

Elasticity
Review of stress, strain, displacement, principal stress, Mohr’s circle, invariants.  Equilibrium and compatibility conditions.  Thermal stress.

Stress Analysis
Airy’s stress functions, stresses around hole, conformal mapping.  Contact mechanics, Bousinnesq solution, axisymmetric solutions, tangential forces, Hertzian contact.

Numerical Techniques for Solution of PDE’s
Finite differences, method of successive approximations.  Finite element modeling, theoretical basis, solution sequence and techniques, use of the ANSYS FE package, including individual project.  Solution of elasticity and other problems, static and dynamic solutions.

Modes of Failure
Buckling, jamming.  Fracture, stress intensity, superposition, stability, crack paths, crystals.  Yielding, criteria, crack tip plasticity, Dugdale, Barenblatt, etc., initiation theory.

Indentation
Hertzian fracture, sliding contact, plastic, elastoplastic deformation.  Pointed indenters.  High velocity impact / erosion by solid and liquid particles, impact on glasses, composites, protective coatings.

Tribology
Roughness, characterization, measurement, bearing curve.  Amonton’s laws of friction, theoretical basis.  Wear mechanisms, identification.  Lubrication.  Adhesion.

Optical Fiber Strength & Fatigue
Test techniques, proof testing, reliability predictions, coatings.

If time allows:

Stress Measurement
Photoelasticity, Moiré, speckle, strain gages.

Applied Statistics
