How to model Carbon nano-tubes in ABAQUS

Submitted by p.haghdoust on

Dear Colleagues 

I want to start some research on the Carbon nano - tubes.

In the begining I need to model a CNT in the ABAQUS.

I wrote a code for generating the xyz Coordinates of the atoms in a CNT.

The problem is that I can not import them in abaqus.

Does anyone has an Idea ?



Thanks in advance

Distinguished Researcher to Speak at NJIT on Preventing Bone Loss

Submitted by TanjaLeijs on

Biomedical researcher Stephen C. Cowin will describe a promising model for studying nutrient transport from the vascular system to bone tissue

Preventing bone deterioration is a critical aspect of combating osteoporosis, improving bone implants, and even making long-term space flight possible, such as voyages to Mars and beyond. On April 9, noted biomedical researcher Stephen C. Cowin will describe a promising model for studying nutrient transport from the vascular system to bone tissue, transport that has a direct bearing on the prevention of bone loss.

Fracture mechanics

Hi

i am new new the the field of fracture mechanics i donot how to start it. can some one send some tutorial or other kind of help in doing fracture mechanics of nanocomposite using any software. Tutorials even of composites fracture mechanics using software so that i can have a idea about the fracture. 

thanks in advance

Postdoctoral Position Available at University of Western Ontario,Canada

Submitted by Zhi Yan on

Position is available for a postdoctoral fellow to carry out an industry sponsored project on carbon fiber composite modeling. The contract is initiated for one year, with possible extension if work progresses satisfactorily. The research will focus on



 (1)  micromechanics modeling of elastic and viscoplastic behavior of injection molded carbon fiber composites;





 (2)  homogenization techniques and constitutive model development for vibration, strength and impact simulations of carbon fiber composites.

Postdoc or PhD position - Multiscale Modeling of Polymer-Matrix-Composites

Submitted by timon.rabczuk@… on

At the chair of Computational Mechanics (chair Prof. T. Rabczuk) at the Bauhaus University Weimar, there is 

1 open position for PhD-student or Post-Doc

for a maximum period of 3 years. The applicant is supposed to work in an international team and should suppose to collaborate with PhD-students and Post-Docs. In this project, effective coarse-graining methods for polymers and polymer-matrix composites should be devised and implemented in our in-house code.

Online finite element analysis of nanoindentation (indentation)

Submitted by sobh on

Dear All, 

 

We (the NanoBIO Node at Illinois ) have a preliminary release of an online finite element analysis of nanoindentation (indentation) tool using FEAP

This preliminary release is limited to linear elastic material, axisymmetric geometry, spherical rigid indenter, and various boundary conditions.
