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

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
research

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

material deposition to substrate simulation at ABAQUS

Hi;

I am trying to simulate material deposition to substrate. In our case material is added to substrate  and there is a distributed heat flux with constant velocity acting by node by node. I want to simulate showing the added material in the simulation and its effects. There is a command for that called Model Change in the ABAQUS. So is someone familiar to that kind of problem. And also I need to account mass diffusivity while the material is melting.

I will be gratefull for any advice you can spare

Best Thanks

Hello, I am Ravindra. I am working on cutting process simulations using ABAQUS software. I am getting some problems in preparing the input file. If anybody has the ".inp" file for cutting process simulation using ABAQUS, please send me. My email address is "aravindra321 [at] yahoo.com". It will be great help.

 

Best Regards,

Ravindra.

Experimental temperature field at the crack tip in a natural rubber

Dear colleagues, this is a paper on the experimental determination of temperature field at the crack tip in a natural rubber using a motion compensation technique. The contribution of the non-uniformity of the IR detectors and the Narcissus effect is taking into account to determine the temperature field.

crystallizable natural rubber

This is a study dealing with the volume variation in filled crystallizable natural (F-NR) and uncrystallizable styrene butadiene (F-SBR) rubbers subjected to cyclic loadings. During their deformation, such materials exhibit volume variation induced by the cavitation phenomenon and the decohesion between particles and the rubber matrix.
