FEA modelling with ABAQUS 6.6 of three roller Flow forming process.

Submitted by probaluwo on

Hi

this is Probal from university of western ontario (UWO). I am working on three roller flow forming process and i have to model the deformation specially in the splined area. could you please give me any idea or give any link so that i can have an idea what to do.

thank you probal 

Modeling concrete wrapped CFRP sheet using ANSYS

Choose a channel featured in the header of iMechanica

Hi all

 

I am currently in my Master Degree in Civil Engineering at University of Michigan. I am doing a research on concrete wrapped CFRP sheets and I want to do Finite Element Analysis using ANSYS. I am not able to model concrete in ANSYS. Can anyone please help me out with that.

 

Awaiting the reply....

 

Thank you

Greetings to all Imechanicans ! ,

I just started using the scripting interface in Abaqus, and i stumbled into a small issue, I have a sample input file which is a small model for crack simulation and its UEL subroutine, I know how to open the input file  but I don't know how to open the UEL subroutine that goes with it, I get the following error :

The model "projGH" has been created.

Quasi Linear Viscoelasticity vs. Linear Viscoelasticity

Submitted by Gungho on

Can anyone explain what is main difference between Linear Viscoelasticity vs qlv (Quasi linear Viscoelasticity) proposed by Fung.  As far as I understand stress relaxation function and elastic response functions separated and given in convolution form which provides "strain rate independent" results in qlv application.  



Is linear viscoelastic description is strain dependent?



Hashin damage model for fiber reinforced composite in ABAQUS

Submitted by Gyanender Singh on

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.
