Hi friends,

I'm going to model a composite plate in ansys but I have few information about it. I need to know the exact procedure of selecting material ID and attributing to lay-ups and also to mesh the domain.This is a 5 layer laminate to analyse uniaxial buckling. I would be thankful for providing me with your friendly notes. 

All the best,

I want to simulate the crack growth under cycle load through ANSYS

I have thought two way to simulate it, first way is cohesive model(debonding)

second way is remesh(rezone at certain load step), this way is important for me, since this method mapsolves the new mesh into the old mesh, so the plastic strain information near crack tip element could transfer to new mesh.

I need a example file(code-command file of ansys) or comment

Dear colleagues,

First time in iMechanica. As a presentation, I am a researcher interested in Fluids and Solids Mechanics. My approach to research involves an interplay between experimental, theoretical and numerical modeling techniques. My principal research areas might be categorized as: Fluid-Structure-Thermal Interaction, Aeroelasticity, Material Resistance, Rotating flows, Mechanical Instabilities.

Hi

If I have a 3d rectangular room,  and I want to model 1/2 of that room because of symmetry boundary condition. in acousticFEM problem, what is my symmetry boundary condition in symmetry plane?

I mean at seymmetry plane which kind of constraint I should apply on pressure of the sound wave?

thanks alot

Hi all,

1. A new version of Eigen (v 3.0 now) is out (on March 23, 2011), and it seems promising. First, a few links:

The main page for the project is here: [^]. The page for v.3.0 is here: [^]. It seems to be very fast: [^].

dear my friends!:

 i doult whether the value of K caculated by ANSYS is proper for a cracked model with Ramberg-Osgood constitutive relationship?
