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,

Growth kinetics of precipitates: misfitting and non-misfitting

Submitted by Mogadalai Gururajan on

Quantitative studies on diffusional growth of an isolated
precipitate in a supersaturated matrix date back to the classic work of
C Zener (1949) and F C Frank
(1950); while Zener-Frank (ZF) theory is for precipitates that are
non-misfitting, misfitting precipitates have been studied by Laraia,
Johnson and Voorhees (1988) (hereafter, LJV). Both ZF and LJV are sharp
interface models (and are mostly analytical); further, the assumptions
made in these theories make it difficult to verify their results by
