Hi All

Is there any research about  interfacial adhesion of  transferrable monolayers and substrates ? I found it's quite different from the rough surface model, because the monolayer is flexible enough to match the roughness of surface. Can one determine the separation value from the different roughness of pure substrate and substrate with a monolayer ?

Can someone give me some clue ? Thanks a lot!

Hello,

Is there anyone out there that can suggest a suitable subroutine in abaqus for modeling anisotropy. I know about the potential option in abaqus CAE that uses hill`s criteria to define different yield ratios in different directions but the aluminum alloy i`m working with is almost isotrop at yield limit but strongly anisotrop at ultimate tensile stress and in plastic strain . So i need to use a subroutine that takes all these properties into considration.

I appreciate any help

According to the Japan Science and Technology Agency (JST), Japanese Scientists invented “Elastic Water”.

who  can tell me more about the critical thickness theory ?I will be very excited if you   can introduce some reference to me.I know that critical thickness theory is solved rigorously and ursed to validated a useful approximation which is combined with slip distance theory modified for a finite structure size . (physical life review letters :elastic limit and strain hardening of thin wires in torsion)

At the stage of NPP civil structure design for determination of stress-strain state (SSS) at static and dynamic loading ABAQUS is widely used. Hereto the floor response spectra are determined for calculation of loadings on the equipment at special dynamic impacts (seismic, air shock wave, aircraft crash). In case if the obtained characteristics of SSS or spectral accelerations exceed maximum permissible values, designers take actions on strengthening the corresponding structural components.
