Hello,

Can anyone send me the paper by P A Cundall and RD Hart.Title of paper is NUMERICAL MODELLING OF
DISCONTINUA.It came in Engineering Computations journal paper (1992).I need it for my research work. thank you. rajeshpnair [at] gmail.com

Post-doctoral position is available in the area of ultrasonic material characterization and nondestructive evaluation (strong background and experience in ultrasonic experiment and modeling are required). The position is supported from research grants. The focus area is ultrasonic study of nonhomogenous materials like polycrystalline materials, composites and adhesive bonds. State of the art ultrasonic laboratories and other characterization facilities are available. More details will be provided to interested individuals.

Interested candidates should contact

Adhesion has long been an important issue for mechanics and
many other disciplines. Its influence spans macro-, micro-, nano- and molecular
scales. When size goes down, adhesion plays a more and more significant role.
Many important technologies attribute to adhesion, such as transfer printing
for advanced microfabrication, super adhesives inspired by gecko foot hairs,
and self-assembly. Adhesion also has strong implications on the behavior of
nanomaterials (such as nanotubes and graphenes) and biological systems (such as
cells). This minisymposium "Mechanics of Adhesion" is to provide a

You can see practical model of cam follower mechanism for clean energy.
Follower move little bit and help cam to rotate 6 times more peripheral
length. Cam can rotate 360 degree using two followers. You can get full
research at my blog at

If research projects are funded by public money, shouldn't their
results be available to the public at a reasonable price? or even free
of charge?

To prevent the monopolization of the scholarly record, read, think, and, hopefuly, support this cause. It is all I ask.

 I want to model reinforced concrete beam- column joint in ansys software.i choose the solid 65 for concrete and link8 for steel.

how can i model the stirrups?

Dear All,

Please explain me what is central differnce operator, what is the role of central differnce played in Abaqus/Explcit analysis

A few points that might be of general interest:

1. The dates: The date of Huygens' first written down material, which was orally presented to the French Academy of Sciences, is 1678---in contrast to the oft-quoted date of 1690. 1690 was the year of the first, French, publication of these notes (plus other material) in the form of a book.

Hi everybody,

 Can any one explain what is the physical meaning that a stiffness matrix illustrate ? I am a learner at a starting level in this Finite Element Analysis field . There are some questions which I wish to get an idea upon ...

 1. What exactly Stiffness Matrix tells about the structure ? Can you please explain with an example like "Linear Timoshenko Beam or Bernoulli beam or like 4-node plane stress element"....

 2. What is the relation between the eigen values of a stiffness matrix and the corresponding rigid body modes ?
