Protection mechanisms of the iron-plated armor of a deep-sea hydrothermal vent gastropod

Submitted by Haimin Yao on

Dear Colleagues,

I would like to bring your attention to our latest PNAS paper which
was just published on-line in Early Edition. This paper focused
on the protection mechanism of the unique snail (Crysomallon squamiferum) shell from deep-sea hydrothermal environment. It is an Open Access Article. You can download it freely by clicking HERE or the attachment.

Samrt material

Submitted by uni_students2009 on

hello everyone

A question how is possible in the same material and in the same temprature we observe some different material properties? as we can see in shape alloy effect? I appreciate if somebody give me some clues as a light to shed the research way. thank you in advance.

Self piercing riveted joint

Submitted by manibijju on

Hello,

I am working on Self piercing riveted joints and trying to simulate using Lsdyna,iam using piecewise linear plastic material model. The rivet is not able to pierce into the sheets, insted it is compressing the elements and elongating them. 4-noded shell elements where used. i want to know how will the elements get broken up or removed from the path of the rivet, I have used one way erode contact card but it was of no use. If any one can suggest  me how the approch should be i would be a great help.

Dear all,

 I'm new to ABAQUS and I was wondering if we could have access to any constitutive equation in ABAQUS and add another stress tensor to the Cauchy stress tensor?

A new book chapter of the role of the actin cytoskeleton in mechanosensation

Submitted by Tian Zhi Luo on

We wrote a book chapter about the role of the actin cytoskeleton in mechanosensation. The book title is Mechanosensitivity and Mechanotransduction, edited by A, Kamkin and I. Kiseleva and published by Springer-Verlag, New York.". 

In this chapter, we try to integrate mechanics, materials science, biophysics and biology together to give a most updated view of this field. We also want to introduce the feedback loop concept to mechanicians who are interested in studying biological systems.

Molecular dynamic simulation on Projectile

Submitted by Shuozhi Xu on

Hi, everyone~

Has anyone done MD simulation about projectile? Like a rigid body penetrating a thin target? I have recently heard that a group in Uni of southern california did such a simulation before. I will be appreciated if someone could afford me some information.

Thanks in advance.

Promotion at random is better! Tenure makes you more "incompetent" -- Peter's principle proved by two italian scientists!

Submitted by Mike Ciavarella on

If you are upset about promotion system, look at what two italian friends proved recently, which was immediately popular before the paper publication, also because they proved random promotion is more efficient!
