Nonlinear free and forced vibration analysis of a single-walled carbon nanotube using shell model

Submitted by Payam Soltani on

 By :Payam SOLTANI, J SABERIAN, R BAHRAMIAN, A FARSHIDIANFAR

In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is 

investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s 

equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial 

Image Based Modeling for Biomedical Implant Design

Submitted by Simpleware on

We'd like to share a recent publication based on our software, which converts 3D volumetric image data into computational models; this article, published in partnership with MSC Technology, highlights how we've been able to produce successful FE models for biomedical implant design.

We have more case studies and information available on our website - www.simpleware.com - where you can also download a free 30 day trial of our software.

Fracture in rock using ABAQUS

Submitted by Sivakumar2013 on

Hi,

Im doing my research in crack initiation and propagation in rock and i have adopted ABAQUS to do this problem. But i cannot find any tutorial for crack growth in rock. As per some random literature i started using XFEM model to model the crack growth. But i still didnt feel confident about my work. Can anyone suggest me some material and im beginner to ABAQUS tool

Behaviourof non linear material under a load

Submitted by arjunkarun on

I am currently working on developing a model of flexible pavement. The middle layer is having a non linear elasticity property. So the elastcity of the different parts of the layer varies with the stress applied. The process continues till the Elasticty stabilises. Can anyon please help me with its implementation in ANSYS APDL?

Visualizing LAMMPS molecular dynamics trajectories using visual molecular dynamics (VMD)

Submitted by Nuwan Dewapriya on

It is very important to visualize molecular dynamics (MD) trajectories since there are many aspects of MD simulations which are difficult to identify without a proper visualization tool. Improper bounday condition in MD is one of such examples. I use Visual Molecular Dynamics (VMD) to visualize my MD simulations. Some of my movies, created using VMD, are shown below.

how to model masonry wall in abaqus

Submitted by eng.femiran on

here we are to tell you how we can model masonry in abaqus cae.
there are 3 ways:
1-micro modeling
2- macro modeling
3- micro-macro modeling(HOMOGENIZATION)
micro modeling; 
in this method all parts should be modeled in abaqus separately.
but notice that don't use shell to modeling grout because of 3d properties of grout and cohesive characteristics.
this method is suitable for small masonry panels with 2-3 layers of brick.
