Xu and Needleman: Potential function in 3-D

Submitted by Truong on

Dear all,

I am improving the cohesive zone model in 2-D proposed by Y.F. Gao to simulate delamination between sub-micron thick films in 3-D. However, I did not find the potential function proposed by Xu and Needleman in 3-D. If you know it please tell me

Here is the potential function proposed by of Xu and Needleman in 2-D (in Y.F Gao’s paper)

Application for P.h.D Position in Civil Engieering

Submitted by h.l.Li on

hi,all

  I am glad that i can get much information about P.h.D position here.Now i have been attending my p.h.d in HuNan Universtiy in China for one year,majoring in civil engineering.I am working about bridge engineering and wind resistance.In China,goverment has provides some opportunity to co-cultivate with other international University.It meas that i can go abroad for some time,say one to two years,to study.But first i should get a invitation from them.Who can give me some information about P.h.D position.any reply is appreciated.

Muskhelishvili's method of estimating USING COMPLEX POTENTIALS

Submitted by Ilias I. Tourl… on

I'm looking for resources for reading and studing concerning the Muskhelishvili's method of estimating the stresses and desplacement fields for singular states of stresses using complex potentials from given boundaries as they mentioned in Timoshenko's book 'theory of elasticity ' pages:203..209.

I tried in my school library and i found nothing.

Thanks in anycase

A new theory of stress?

Submitted by Biswajit Banerjee on

I was browsing the discussion page for Stress in Wikipedia when I came upon this interesting comment:

"

Refutation of Cauchy stress

The theory of stress based on Euler & Cauchy is now refuted. The profound incompatibility of this theory with the rest of physics, especially the theory of potentials and the theory of thermodynamics, has been documented in

Surface and Grain boundary

Submitted by Xu Zhang on

Surface:

If it's a free surface, the dislocation can penetrate through the surface easily, but, if it's a coating or oxide layer, it will be hard for dislocation to glid out of the surface

Grain boundary:

In discrete dislocation dynamic simulation, some authors take grain boundary as a impenetrable, such as a rigide wall, But in other papers, grain boundary was thought to be a penetrable wall.

 So,Is there somthing or simillar property for us to derive.
