Anybody who can send me some Xfem code.

Hello,

    I am a PhD student in Xi'an, China.

    I am studying  some XFEM related papers, to start coding the method, I thought it would be easier if I go through a code for a basic XFEM problem.

   If anybody who have  the code, please send it to me.

    Thank You. 

 

How we can calculate stress intensity factor for bimaterial interface

Submitted by kaslantas on
research

Hi friends,

I would like to calculate stress intensity factor for bimaterial interface using finite element method. Do you have any suggestion about it? Actually I know a method. According to this method,

1-obtain crack face displacement using numerical solution

2- use dundur parameter 

 

Is this method is correct/enough?

 

As you know Franc2D code calcuate SIF for mode I and mode I. But I do not know this code can calculate SIF for bimaterial interface? 

Thanks

Dear all 

i am a new abaqus user, now i use this software to modeling a few layers of soil layers (in geotechnical engineering), here is the information of the ground profile

[0-4m] fill sand layer; Density = 18kN/m2, firction angle=30, cohesion=0, void ratio=0.5  

[4-12m] marine deposit; Density = 16kN/m2, firction angle=10, cohesion=30, void ratio=0.5   

[12-22m]  Alluvium; Density = 18kN/m2, firction angle=30, cohesion=5, void ratio=0.5

plate
RBF

Hello,

i'm working on the modeling of thin plate under transverse load. The basic function used for approximation of field variable is RBF function. There are a lot of publications, how the static model of the plate can be created, but no information about dynamic modeling. The following questions are not clear for me:

ABAQUS : Programing Sandwich plate with Complex Shear modulus core

Submitted by chlif_med on

Hello;

To study the vibration of a sandwich plate I evaluate the complex shear modulus with the GHM method.

Can you tell me how I can enter the complex shear modulus in ABAQUS:

Gv := 0.142*((w/(2*Pi))^0.494)*(1+1.46*I)*1e6 

(I^2=-1 , w =2*Pi*f  , f: frequency)



Greetings
