Course: MS 211A/ MAE 229A MECHANICAL PROPERTIES, FALL 2003
Final Exam: Tuesday, December
Textbook: M. A. Meyers and K. K. Chawla
This course is intended to bridge the gap between mechanics and materials. Its purpose course is to provide the student with an in-depth and quantitative understanding of the physics of deformation and fracture. Mechanics and Materials are two disciplines that can benefit enormously from each other. Unfortunately, they have been most often taught in separate departments, to separate audiences. A focused effort has been carried out at UCSD, since 1992, to link Mechanics and Materials. This was the mission of the NSF Institute for Mechanics and Materials, which had a six-year life. Five Summer Schools were held, with a participation of approximately 300 students. Lecturers included the most renowned scholars in the field. A book was published in 1999, based on these lectures. It is the recommended reading for this class, in addition to the textbook. The book is:
Mechanics and Materials: Fundamentals and Linkages, Eds.: M.A. Meyers, R. W. Armstrong, and H.O.K Kirchner, J. Wiley, 1999 (MM)
Meyers and K.K. Chawla, Mechanical Behavior of Materials,
It is, of course, recognized that the entire field cannot be covered in one quarter. Nevertheless, the students are encouraged to purchase the textbook and recommended books to get exposed to the seminal concepts. The following topics will be covered in class:
Stress concentration around holes and cracks MC1
Elements of fracture mechanics MC1
Microstructural effects MC1
Thermally activated processes MM
Zerilli - Armstrong and MTS models MM
Mechanical twinning; mechanical effects MM
Obstacles to dislocations MC1
Plastic deformation of polymers and glasses MC1, MC2 & handouts
Constitutive equations for deformation of polymers and elastomers handouts
Basic mechanisms and constitutive equations for creep MC1
Grading, Exams and Homework
Grading will be based on exams, homework, and a report.
The weights will be:
a) A brief statement of the problem including any necessary given information or
assumptions you decide to make.
c) Mathematical analysis
d) Your final answer with a BOX drawn around it. This is essential!
Do not carry around symbols for units as you walk through a problem. When you give a
final answer, then is the time and place to attach units. Use the abbreviations in the text for Mega Pascal (MPa), density (g/cm³), etc. Don't forget correct units.
