In the figure I showed a mechanism, I want to make an analysis for that. consider the circles in the figure as cylenders which can be seen in the top view. these circles are regular cylenderical parts. I made the fig in paint thats why circle don't seem to be regular. I want to analyze the angle that at given angle, whether the rolling flow of these cylenders will be blocked or not. Please tell me some software to analyze in 2d Prefferably or 3d. Please help me. I'm in intense need.

ANSYS claasic

Hello ANSYS  users,

 

I am having hard time ANSYS's documentation for fatigue analysis in claasic environment. Tutorials available on internet talk bat ansys workbench only. Has anyone done fatigue analysis in ANSYS claasic? If yes, is there any source for tutorials ?

 

Thanks,

 

How to represent a "bird" in ABAQUS

ABAQUS
Porperties of bird

Dear all,

   I will model a bird to impact a shell at high velocity by ABAQUS.  I decide to model the "bird" by ALE mesh and referred by EOS equation.

   However, most simulation works are done by LS-Dyna. Do anyone know how to determine the parameters in ABAQUS for the "bird" in EOS equation?

   All suggestions are welcome.

   Thanks.

 

Jason,

Best regards 

Remeshing in Abaqus/ Explicit

Submitted by tahsinopoz on
software

Hi Dear IMechanica User

I have faced up a problem during micro-scale cutting using abrasives. I am trying to model this process using Abaqus/explicit and with remeshing module. but currently there doesnt exist any remeshing technique in abaqus/explicit. Could you please suggest the way for doing this simulation by using remeshing technique in Abaqus/explicit. Abaqus/standard is not helpfull to model cutting simulation. this is because i am using Abaqus/explicit by the way.

 

I am awaiting your valuable suggestions and helpfull informations.

Good evening,

in the order to perfom a calculation of Tsai-Wu Fc in Ansys there are two fundamentally different methods:

1. with the help of nodal stresses.

2. or with the stresses from the element table.

I want to know what is the difference, and which method, according to your experience is the best.

Thank you very much!
