ABAQUS : Programing Sandwich plate with Complex Shear modulus core

Submitted by chlif_med on Tue, 03/03/2009 - 07:18

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)

aspect ratio

Submitted by g_rakesh2 on Tue, 03/03/2009 - 06:56

what should be aspect ratio of the geometry? meaning larger dimension of geometry to shorter dimension of the geometry.

when one uses element type as solid45!!

please help..

Thanks in advance......

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 Mon, 03/02/2009 - 13:42

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

Visual Fotran 7.61

Submitted by albanna on Mon, 03/02/2009 - 05:48

visual fotran. subroutine. ABAQUS 6.5

Anyone here who has an experience run a subroutine by using Visual Fotran 7.61. Can we run subroutine from VF 7.61 with ABAQUS 6.5? Is it compatible both together?

Please help me!

Thanks.

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.
