Help Regarding composite material Analysis in Ansys

hello to all,

                 I m new to composite material analysis, I am  doing a project for wind turbine analysis in ansys. The wind turbine contains total 96 layers of two different material which is stacked alternatlly. i dont know about the modelling and analysis procedure of composites. i don't understand how to connect the surfaces.

                 thanking you..............

Ansys File Import

I am working on a FEM project in which i should import a complicated 3D model to Ansys.

 I created The IGES format of the model which the size was 52Mb for the IGES file.The model contains very curvy surfaces and it is complicated.it is created By 3D doctor....

 

when i import it to ANSYS it doesnt create any volume and i can see only small areas. 

now how can i make the model more handy for ansys....also i need to have a volume in order to meshing....

could u please help me to get out through this?

Thanks 

Computing Thermal Stresses for Composite using ABAQUS/CAE

Hi,

I am new in ABAQUS. I am trying to find the thermal stresses created by change in temparature of 50'C for lainate consisting of [90/+45/-45/0]s configuration. Eventually what I intend to do is find the stresses under a simple uniaxial load which also consider the change of temperature while calculating the stresses in each ply. I have the material data for the coefficinet of thermal expansion both for longitudinal and trnasverse directions (alpha_11 and alpha_22).

Is there any suggetion of approches I may take.

Many thanks in advane !!!!

 

Regards

How can I model the progressive damage of composite materials

Recently, I indulged myself into the progressive damage simulation of composite materials. I firstly used the USDFLS to create several fields to define certain kinds of damage, such as fiber crack, matrix crack, shear damage and delamination. One curious thing that I experienced into this is that ABAQUS/Standard informed me that "Stiffness defined by engineering constants is not physically reasonable. Check choice of poisson's ratios". I checked the data and changed some to comply with the rules of the transversely isotropic materials and the program proceeded.

Hi Friends

I would like to get informations about ABAQUS aqua which is being used for offshore analysis, if any one have anything about that subject including (tutorials , examples and notes ) I would be grateful to him in providing me with.

Thank you all

I want to do modal analysis of a simple structure under the effect of residual stress. How can I do it in Abaqus ?? I need the precise steps to do with the GUI.

How the abaqus calculate the energy ?

How the abaqus calculate the energy ? such as ALLSE  ALLCD  ALLKE......all the energy variables.

what is the eaxct  equations?

all the abaqus manuals hadn't say something about the equations to calculate the energy.

ANSYS Mechanical Thermal Analysis - Average Temperature

I've a result from thermal transient analysis. The result shows the maximum and minimum temperature of 4cm * 4cm plate with thickness of 1 mm.

Since the temperature of that plate is not uniform, so I'd like to see the average temperature from overall plate. How can I do it?

Thank you.

ABAQUS - Beam, Plane Stress, and Plane Strain Element Compatibility

Choose a channel featured in the header of iMechanica: 

Hello,

 

I am working with a simulation of a thin component bonded to a thick
component in ABAQUS 6.7.  Here I utilize beam (B21) elements bonded to
plane strain elements (CPE4R) using a *TIE constraint, and another
simulation that uses plane stress elements (CPS4R) bonded to plane
strain elements (CPE4R) using a *TIE constraint.  In both cases the
plane strain elements represent the slave surface for the bonded
constraint.

Extrude a solid section

Hi all,

       I am having some troubles with the extrude command in Abaqus cae. I have modeled my sample as a 2-D geometry and now I want to move to 3-D for the same section. But I am having trouble extruding my 2-D section. It seems to me very weird and far to complicated the extrusion process in abaqus for such a simple task...

Thank you,

Abaqus "initial condtions"

Am writing as a statement in my model the option initial conditions, am not sure where is the excat palce so i run my file to identify the error "as follows" but still not knowing where to do so?!! (it said under level: Model)!!!

Thank you!

simulation of the resonance of a metal structure ansys 12.1

hello
is it possible to load (or simple harmonic ...) this structure to make it resonates and see the amplified strains.
What are the steps:
- I have already started extracting the natural frequencies (modal analysis I took 6 modes).
- I still have to apply a harmonic load F (t) = f 0 cos (alpha * t), I can not make this charge (I froze here)
- Instead it will force following the direction of the first response of the structure (the first nature-value) in the direction of the distortion along the + y axis (blue arrow)

STUDY OF THE THERMAL BEHAVIOUR OF DRY CONTACTS IN THE BRAKE DISCS « APPLICATION OF SOFTWARE ANSYS v11.0»

Abstract: The braking operation is a process which converts the kinetic energy and the potential energy of the vehicle into other energies. The major part of the mechanical energy is transformed into heat. During the braking phase, the frictional heat generated at the interface disc - pads can lead to high temperatures.

[ANSYS] Composites. Problems using shell181 at postproc and tsai-hill criterion

Hi all,

I've modeled a composite sandwitch with ANSYS with a pressure. The element chosen was SHELL181.
I want to know the Stresses in the x, y and xy directions; the displacements and the deformations only in a few points so as to compare with the Navier and Rayleigh-Ritz solutions made following Reddy's book.

1.-The first problem is that I don't know how to ask ANSYS to list the displacements and deformations.

2.-The second one is that I know how to ask ANSYS to list all the elements in a layer,
