stress singularity and stress relationship

Submitted by msd.jacob on Fri, 07/13/2007 - 11:15

Dear All

Williams analysis is well known for stress singularity. Actually when we are analysing the stress distributions between two diffrent configuration which is given below ,based on the stress singularity, I got a doubt...how the order of stress singularity is directly related with the stress. (we can get the relationship using equation) however if i want to explain to a student who never come across with applied mechanics. How can we explain to him in very simple and understandable manner.

Lateral Force Microscopy

AFM

I would like to do lateral force microscopy on biological samples. The more I look into it, it seems it is very difficult to calibrate AFM tips for lateral force microscopy. Does anyone have any suggestions about how to calibrate tips and which tips are conducive for lateral AFM?

Body loads in wave propagation..

Submitted by ramdas chennamsetti on Thu, 07/12/2007 - 08:33

Hi all,

[1] In solids, the wave propagation equation is obtained from stress equilibrium equations. We make use of constitutive and strain-displacement relations to convert these equations in terms of displacements

[2] In the above equations we assume that there are no body loads.

[3] The form of solution we assume for displacements is harmonic

[4] Plug these three displacements, u1, u2 and u3 in the equilibrium equations stated in [1].

[5] We end up with an Eigenvalue problem. This is nice.

conference

If you are interested by the mechanics of elastomers, there is a dedicated conference for you : ECCMR 5, which will be held in Paris, France, 4-7 September 2007.

It is the fifth edition of the European Conference on Constitutive Models for Rubber Conference. The call for paper is now closed, but registration is still open.

American Academy of Mechanics

As a member society of the U.S. National Committee on Theoretical and Applied Mechanics (USNC/TAM) , the objective of the American Academy of Mechanics (AAM) is the advancement of the science and profession of mechanics.

The scope of AAM includes all of the disciplines involved in the modeling and study of the response of inanimate and animate matter to forces and environmental effects.

Why is Google cool, but Elsevier is not?

Submitted by Zhigang Suo on Wed, 07/11/2007 - 11:41

Elsevier-bashing has become a sport among researchers. The company is singled out, among publishers of research journals, perhaps because it is the largest. We might as well use Elsevier as a representative of the publishers, and hard-working people at Elsevier should not be offended.
