It is a 3D cubic cell model out of a whole material,  and it is necessary to make sure that this cell can represent the whole material so the node forece of the corresponding nodes on the opposite surface should have the same value and opposite direction, but I have no idea about how to control the nodes force (maybe *EQUATION ?), because untill now all the boundary control method is about controlling the displacement. Does anybody know how? Thank you guys so much!

Hi,

with the Ansys Help I can see the graphic modes. But I need them as a vector (or the modal matrix) to get with the eigenfrequencies the mass matrix and the stiffnessmatrix of a dynamic system.

How can I import those modes for example into Matlab or into an excel program.

Can anyone explain what is main difference between Linear Viscoelasticity vs qlv (Quasi linear Viscoelasticity) proposed by Fung.  As far as I understand stress relaxation function and elastic response functions separated and given in convolution form which provides "strain rate independent" results in qlv application.  



Is linear viscoelastic description is strain dependent?

I love seeing the applications of our engineering accomplishments. The new KERS systems in the Formula 1 racing cars will hopefully bring interest to the common masses in regards to engineering, mechanics, electrical energy and hybrid technology development. Having this technology in the high visibility realm is sure to create positive ripples in our direction. They are adding a 80hp electrical motor between the fuel system and engine to add small bursts of power. This is powered generated from braking and stored in a ion-lithium battery pack. 

thanks a lot

Iam beginner in ansys, so i have problem in enter the steps of cyclic load to a plate as solved in ansys to get the deformation with time curve.

can any help me??

Hi Everyone,

I am doing a project in which I am trying to study about the
drilling of composite. The aim is to optimize the drill and process
parameters to minimize the damage. For this I have tried to simulate
the drilling process in ABAQUS and I am using the Hashin damage model.
The problem is that Hashin damage model works only for the lamina which
takes only plane stress elements. Since only plane elements are allowed
I am unable to simulate cutting action of drill as the composite plate
is effectively 2D.

Hello freinds

I am facing problems with ABAQUS in doing the transient temperature analysis,and creep analaysis,,

can any one sujjest me about the porcedure step by step in ABAQUS for solving the heat trasfer problems and creep anlyisis rpoblems..

it willl be help ful for me ..please............

and one more question how can i fine online tutorials for ABAQUS 6.1.6

please guide me by sujjestting the solutons for aboove problems..

i am struck with these problems cant able to continue my research...please consider me..

Hi everyone,

I am working on a personal Fatigue Analysis code that read nodes and stresses from FE processors. I would like to read the NASTRAN .op2 output  file. Does anyone know about the structure of this kind of file?

Thanks,

Ademar.

hi

could you give some suggestion ,which how can i use strand7 to analysis the membrance with  hole?
