Experiment 3: Mechanical Testing- Tensile Testing
The mechanical properties of a material are directly related to the response of the material when it's subjected to mechanical stresses. Since characteristic phenomena or behavior occur at discrete engineering stress and strain levels, the basic mechanical properties of a material are found by determining the stresses and corresponding strains for various critical occurrences.
How to read new comments at a glance?
As the number of comments increases rapidly, how can anyone keep up? One answer is to use a RSS reader. The service is free, and takes 5 minutes to set up. It allows you to see all new comments at a glance, without clicking on individual ones. Once you have set up your Google Reader, paste the URL for the feed of comments crss

Experiment 2: Mechanical Testing- Impact & Hardness Testing
The mechanical properties of materials are ascertained by performing carefully designed laboratory experiments that replicate, as nearly as practical, the service conditions.

Experiment 1: Crystal Structure: X - Ray Diffraction
The X-Ray diffraction technique is used to determine the crystal structure and interatomic spacing of crystallinesamples through constructive interference of reflected x-ray beams.
Bragg's Law and X-Ray diffraction data, in combination with the expressions for interatomic spacing in terms of the lattice parameter and Miller indices for acrystal, can be utilized to identify crystal structures, determine lattice constants, and locate defects within astructure.
materials of engineering laboratory
In the spring semester of 2002, Dr. Woldesenbet and I gave a hand-on laboratory course: Materials of Engineering Laboratory, to the junior undergraduate students at the Louisiana State University. In this Blog, I am also adding some state-of-the-art techniques for materials laboratory.

Movie of an expanding ring experiment
I have posted a movie showing a ring expansion experiment. A thin aluminum ring is made to expand through electromagnetic interaction at strain rates of about 10^4 per second. As the strain increases, numerous necks and fragments appear.
