Crack Analyze Using Analysis Based On API 579 Crack Like Flaws

I'm doing final project in the area for Crack Like Flaws based API 579.  I'm having trouble with level 3 Assessment Procedure and should using ANSYS to solve problem.  Is there anyone who have complete step by step procedure in Crack analysis using ANSYS based API 579 for level 3 ?

how to model composite laminates in ANSYS v11

hello everybody;

i'm doing finite element modal analysis of composite structure using ANSYS v11. however i got problem with modeling  composite laminates. i hope someone can show an example on how to model the composite laminates. i had looking for the related tutorial but couldn't found one.

nonuniform surface traction in abaqus .

Hello everyone:

 recently i encountered a problem when using abaqus .i wanna define shear distributed load along a surface,

the magnitude of a single point is related with  its velocity.but it looks that abaqus does not support this kind

of load even in VDOLAD .how can i do to realize it?

thks a lot .

Iterations in VUMAT

Dear all,

I' m trying to make a model in VUMAT for shape memory alloy based on Lagoudas 's thermomechanical constitutive model. It seems that It's necessary an iteration to evaluate the thermoelastic prediction.

My questions are : is it possible to use an iterative loop in the VUMAT or it's better to avoid it??Could someone suggest me a different way so that I can avoid the iterative loop?

Many thanks,

Cece

how to define the STEPs for earthquake analysis at ABAQUS software

Dear all

I want to know how to define step module for the earthquake analysis specially adjusting a parameter for Dynamic Explicit…like  “TIME PERIOD” and the other parameter.


Design software

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.


Fatigue analysis in ANSYS claasic environment !!

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,

 


helping in Ansys modeling

Hey people

I am new user to Ansys software in area of mechanics of material. I would like to do some  stress analysis in a specimen constructed of multilayers from different material. my interest is to study the problem using Ansys finite element software to support the expermental work and analytical computation . can any body give me any tought how to use cohesive zone model or any other options which are available in this modeling tool. also if there is any tutorial that can be helpful. I would like to connect will people how have worked or still been working with these kind of problems.

thanks in advance.

How to represent a "bird" in ABAQUS

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

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.

 Thsnks

 Regards

Tsai-Wu Fc with Ansys

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!

Computing of subdomain integration in Abaqus

I am woring on homogenization with Abaqus for predicting effective properties of composite material, I am using Abaqus to implement  homogenization method, now, I need to compute the stress integration in a subdomain in Abaqus, but I do not know the keyword to do that. Any suggestion is very much appreciated.

 

Thanks in advance


Implementation of Isotropic, Kinematic & Combined Hardening laws in Ansys 11.0

Hi Everyone,


I'm analysing the Edge waviness which is caused in the sheet metal when it is undergoing the electrolytic coating process (zinc galvanising plant). i.e. there is waviness (shakes) in one edge side of the sheet metal.

In this process the sheet metal has to go a set of conductor rollers, electrolytic solution and support rollers, where the sheet metal is been loaded when it comes in contact with the roller and unloaded when it moving away from the roller. i.e. it has to undergo stretching, bending and cyclic hardening behavior due to loading & unloading.
