Hello Everyone,

I am a beginner in FEA of composites under impact in commercial explicit code Pam Crash.I want to know why the behaviour of composite plies with CDM approach show mesh dependency?Or a more general question for me is that what makes the FE simulation of a material with strain softening behavior mesh dependence(If this conclusion is right)? Does it make any difference with regard to mesh dependency if one uses implicit codes??

Thanks

Hi all,

             I would like to ask how is it possible to import  a sketch or a part into Abaqus without using any other software needed, like CATIA, PARASOLID etc... Currently I am using Matlab to create my geometry. What I obtain is my exact geometry in terms of points given by x,y and z coordinates in txt format or inp format. But still struggle to import my geometry into Abaqus. Any help, more than welcome...

Best regards,

Dear all,

please find information about the 5 day - course on Plasticity and Microstructures at CISM Udine, Italy.

viscoelasticity  ----ABAQUS

Dear Guys,

I AM NEW PHD STUDENT and my project is to build a finite eleminte model based on MRI data of an index finger and the tissue inside it.  I'm wondering how to start it and what is the best way to go about it.  I've not covered all the aspects of my project or the first step to start it.  I'm looking for some advice regarding this.

Thanks for your reply

hi

please wgo can tell me what does mean the folowings:

   -", the modulus ratio in the first term in the Prony series expansion of the shear relaxation modulus."

   -", the modulus ratio in the first term in the Prony series expansion of the bulk relaxation modulus."

and how to calculate them in abaqus

thanks 

Hello,

 Am working on post tension prestressed concrete with Abaqus,

1-  I would like to know where to find the "initial conditions option and prestress hold" in which module??

2- Rebar option: as per the Help, it is mentioned that i can define a rebar as individual element not as rebar layer in a shell/membrane element. but also couldn't be able to find how and in which module?

Any suggestions?

Wating for a quick feedback

thanks
