strain evaluation in relaxed nanowires

Submitted by Yongfeng Zhang on Mon, 07/20/2009 - 19:56

Due to the existence of surface stress, the interior of a free standing nanowire is in non-zero stress state especially near free surface (see attached). This stress state corresponds to strain field in nanowires. A reference configuration would then be necessary to define the strain. Any good suggestions on the selection of the reference configuration?

delete some objects on a part in abaqus

Submitted by amin_dezfuly on Mon, 07/20/2009 - 17:38

i import a part of ansys to abaqus

this part compose some object in ansys

but when this part import in abaqus --> this part convert a block and i can not delete some object of this part

i want to delet some object of this part in abaqus

please help me

Simulation of FRP in ANSYS

Submitted by omaromar on Mon, 07/20/2009 - 06:05

I make a master research about concrete beam strengthened using FRP strips and u-wraps. i do the FEA for my test samples in ANSYS so,i hope if someone can tell me what the better element is for simulation of strips and which one for u-wraps. another question, is the local axes effective in ansys and how i can control it.

Many thanks

Leonhard Euler has 5 students and 56,850 academic descendents. They are all listed by the Mathematics Genealogy Project. Euler himself was a student of Johann Bernoulli, and produced a student named Joseph Louis Lagrange, who in turn produced Fourier and Poisson. No wonder Euler has so many descendents by now.

I am Cecilia. In 2007 I graduated in mechanical engineering at the University of Cagliari (Sardinia, Italy).

During the degree courses I took several classes on structural mechanics, including, Mechanics of Composite Materials,

Fracture Mechanics, Finite Element Analysis (with Ansys and Abaqus).

Now I am a PHD student at the Univesity of Cagliari and this is the aim of my research:

poroelastic model

I am currently working on a poroelastic model for an oil basin-I have tried and read through Abaqus manual to find out how we can apply Biot's Coefficient in our model or how it takes care of it-Does anyone have any clue about this?
