composite

Hi,

i am looking for a free tool to create radial/radar plot for youngs, shear modulus

and poissons ratio (diagramms showing properties as a function of the angle).

so far i found one excel / vb based one but it is very basic.

Any suggestions?

Hi all,

 I am looking for any literature on the solution the analysis of composite plates with multiple holes in them. I have been able to find plenty of information about single holes in composite plates but none on multiple hole interaction, hence this call for help.

Thank you in advance,

Fernando

Hi Everyone,

I am doing a project in which I am trying to study about the
drilling of composite. The aim is to optimize the drill and process
parameters to minimize the damage. For this I have tried to simulate
the drilling process in ABAQUS and I am using the Hashin damage model.
The problem is that Hashin damage model works only for the lamina which
takes only plane stress elements. Since only plane elements are allowed
I am unable to simulate cutting action of drill as the composite plate
is effectively 2D.

Hello,

 Pardon my basic question.  I need to model a carbon fibre sheet using Abaqus 6.7.  I cannot seem to get the composite layup tool to work properly and I do not know how to define the material properties for carbon fibre.  Are there any good online turorials I can use to do this?  My part will be 8-ply, 125mm square, ~1mm thinck.  Any help is appreciated.

Thanks,

Tyler

Hi All,

I am analysing a fiber composite solid plate with a large and small holes. The model is meshed with C3D8R elements. The output has U and RF in global CSYS and S, E in local CSYS. I have problem in reading  S and E written in local CSYS. I know it is very simple, but I cant able to figure it out. Those who know, how to read the S and E in local CSYS, please help me. Tks in advance for your time and advice.
