How the pressure in ANSYS is implemented?

There are several possibilities for the realization of the presure load.
For
example, when I apply a pressure to an area (lets say, thin rectangular
plate) the area of the plate grows during the deformation process. One
possibility is to keep the pressure per unit area constant (in this case
the total force acting on a plate grows during the deformation) and the
second is to keep constant the total force acting on the plate (in this
case the force per unit area decreases with the deformation). I looked

How to set the element coordinate system for truncated cone composite shell in Ansys ?

Choose a channel featured in the header of iMechanica: 

Hello, everyone! 

Now, I'am trying to analysis a truncated cone composite shell subjefcted to compression load in Ansys. But I don't know how to set the element coordinate system. I want to set the circumferencial direction as fiber direction, and the thickness direction and generatrix direction as transverse direction. Can any one teach me how?

Thankful to any adivice? 

Curve Fitting for Viscoplastic (Anand) Model in ANSYS

Hello everyone, 

            I would like to know if it is possible to use TBFT option in ANSYS to curve-fit Anand's model parameters using experimental force-displacement data.

     I am aware that the ANSYS manual  has description for hyperelastic and even chaboche model, but is there an established procedure to obtain Anand model parameters using experimental curve fitting ? 

 

Thank you.

explicit analysis critical time-step Ansys

hello,

 I am trying to solve a simple cantilever beam (2D)  in ansys.

I wish to find out the critical time-step that can be used to explicitly solve a transient problem. 

 

I started with modal analysis to determine the maximum natural frequency of the model. I then computed dt < 2/Wmax.

I use this dt with beta = 0.0 and gamma = 0.25 (Newmark parameters). However the solution is unstable.

I am including my apdl script with this post.

Explicit Dynamics with ANSYS LS-DYNA training course

This training course covers the ANSYS LS-DYNA Interface, which seamlessly links the ANSYTS traditional environment pre- and post-processing software with the LS-DYNA explicit solver to conduct highly nonlinear, transient dynamic analyses. Sequential solutions are also discussed, in which the ANSYS implicit solver is used in conjunction with the LS-DYNA explicit solver to extend the range of applications.

link 8, introduced tensile curve and compression curve

Hi.

I'm working  with the element link8 (Ansys 12.1) and I have to
introduced the tensile curve and compression curve, but I don't know,
How I have to introduced its???

 

I have worked with the comands: TB: aniso, miso,..., I think the best
option is: TB, user, but How I have to introduced the values of tensile
and compression curve?, when this are different.

 File attachment is the tensile and compression curve to introduce

Thank you, Toni

how to use SHELL 181 element for model light gauge steel lipped channel column in ANSYS

greetings sir.I am doing project COLD ROLLED STEEL lipped channel column
in ANSYS .my question is how to make lipped channel column model by
using shell 181 element or give any other idea to make that model(lipped
channel column)

Is it possible to model nonlinear elasticity in ANSYS with SOLID 18x elements?

Dear all iMechanicians Smile,

Since several days I am trying to simulate a granular material very similar to sand. The uniaxial compression test performed to the material shows a nonlinear elasticity behavior during the unloading curve.

Finit element Analysis of mandible bone with implant

Hi everyone
i work on a bio mechanic project. i am going to simulate a mandible bone
with implant. at first i want to use Materialise Mimics V10 to convert Ct Scan
data of a mandible without implant to a 3D model. i thought i could edit
the exported file on the other software (Ansys or Abaqus) to add the
implant. but, exported file from mimics can not have any edit .Actually
it has not volume and i need to have a 3D solid model. please help me !

ANSYS Contact Elements

Hi,

Please does anyone have a tutorial or an example problem on how to model contact elements in ANSYS?

Thanks for all your help.

Linear Elastic material behaves as Neo-Hookean in ANSYS?

I solve the static bending problem for thin plate under uniformly distributed load acting orthogonally to the plate. I
need the solution up to quite large values of deflection (100
thicknesses, which implies the strains about 100%), but I want to take
into account only geometric nonlinearity and not the material
nonlinearity. I use elements which support large strains (SHELL181,
SHELL281). The software is ANSYS Mechanical APDL 12 and 13. Also, I use "Large displacement static" option for
solution.

how to model the damping behavior of viscoelastic passive damper using ANSYS applied to a sandwich beam

 

 dear all, 

How can I model the changing

Structural analysis of a bullwheel on Ansys

Choose a channel featured in the header of iMechanica: 

Hi everybody,

I have some problems with the structural analysis of an drive bullwheel on Ansys.

How can I apply the load on the bullwheel groove

Tangential (constant) and normal components

 

I was thinking to apply the normal load using a prep>loads>define_loads>apply>FUNCTIONS but I'm not good at this option. Is it necessary to define a particular coordinate system?

FEM modelling of braided composites

I am doing simulation of fiber reinforced composites, for that I have modelled a cubic REV. However , when I am constraining the opposite faces' node displacement sum to be 0 and coupling the nodes in each face in the direction perpendicular to the area, ANSYS is coming out . I have tried this on i7 processor with 8GB RAM system. I am confused if its a RAM problem or a model problem. If there are too many constraints if I apply coupling as well as constraint???
