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)

An additional book, albeit too elementary for the sophisticated (and demanding) graduate students, is:

M.A. Meyers and K.K. Chawla, Mechanical Behavior of Materials, P.-Hall, NJ, 1999(MC2)

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:



Tensor treatment of stresses and strains

Elastic anisotropy (symmetry of crystals and of composites) MC1

Brittle Materials

Stress concentration around holes and cracks MC1

Elements of fracture mechanics MC1

Compressive failure: confinement effects MC2

Microstructural effects MC1

Eshelby inclusion problem-handouts


Ductile Materials

Constitutive description of plastic deformation; engineering equations M

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

Fatigue MC1

Homework: 25


Homework Guidelines


  1.  Homework should be neatly written on standard engineering 8 1/2 x 11 paper.  Sloppy or late homework will be penalized or even rejected.


  1. Be sure to show your work on all homework problems; the answer alone is never responsive, and points will be deducted if important steps are missing from your development.  Make liberal use of carefully drawn and labeled diagrams in your homework.  Since significant partial work is usually given some credit on homework, it is a sound strategy to hand in what you can do on each homework problem.  One more thing:  It must be your own work!  Cases of copying will be treated as ACADEMIC DISHONESTY.  You can talk with other students, but you must then do the problem yourself.


  1. Assignments will be announced in class, typically on Tuesday, and will be due the following Tuesday.  Homework is due at the beginning of class on the due date.  Assignments handed in after the beginning of class will be treated as late and will not be graded.  PLEASE DO NOT ATTEMPT TO COMPLETE ASSIGNMENTS DURING THE LECTURE.  THESE WILL NOT BE GRADED.


  1. Each problem should begin on a NEW PAGE and should include the following:

a)      A brief statement of the problem including any necessary given information or

      assumptions you decide to make.

b)      Figures

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.


  1. No homework will be accepted late (homework is due in class on due dates before class begins).  A late entrance into the class does not provide an excuse for handing homework in late.


  1. Be sure that your name is at the top of the first page of each part.  PRINT your name in block letters, LAST NAME FIRST.  Staple the pages together to ensure full credit.
