Help Regarding composite material Analysis in Ansys

Submitted by xyront on

hello to all,

                 I m new to composite material analysis, I am  doing a project for wind turbine analysis in ansys. The wind turbine contains total 96 layers of two different material which is stacked alternatlly. i dont know about the modelling and analysis procedure of composites. i don't understand how to connect the surfaces.

                 thanking you..............

Ansys File Import

Submitted by vahid2364 on

I am working on a FEM project in which i should import a complicated 3D model to Ansys.

 I created The IGES format of the model which the size was 52Mb for the IGES file.The model contains very curvy surfaces and it is complicated.it is created By 3D doctor....

 

when i import it to ANSYS it doesnt create any volume and i can see only small areas. 

now how can i make the model more handy for ansys....also i need to have a volume in order to meshing....

could u please help me to get out through this?

Thanks 

Computing Thermal Stresses for Composite using ABAQUS/CAE

Submitted by aik_shuvo on

Hi,

I am new in ABAQUS. I am trying to find the thermal stresses created by change in temparature of 50'C for lainate consisting of [90/+45/-45/0]s configuration. Eventually what I intend to do is find the stresses under a simple uniaxial load which also consider the change of temperature while calculating the stresses in each ply. I have the material data for the coefficinet of thermal expansion both for longitudinal and trnasverse directions (alpha_11 and alpha_22).

Is there any suggetion of approches I may take.

Many thanks in advane !!!!

Hi everyone

 
I need a NASA article and I have few information about how to get access to it. Here is its title and hyperlink.

high strain rate in MD simulations

Submitted by Azadeh Sheidaei on

Dear All, 

Recently I have read some literatures on Molecular simulation of polymer. My interest is measurement of

mechanical properties of polymer through the uniaxial tensile test.    

I have a question about relatively large time scales in MD simulations of polymer and how to interpret MD

stress-strain results for FE modeling. In particular, in the literature it is mentioned that strain rate of
