Reading Assignment #2

Strain Measurements

To introduce you to professional papers in measurements and interpretation of strain, I would like you to read two papers, one from each list.

Email abstracts to me by October 23 , 2006.

After reading the papers, prepare a 1-page typed abstract of the paper including what you understood from the paper, including the kernel of the paper, a critique of the methodology, discussion of accuracy and precision, and the importance of the paper.
