How to do a fatigue life prediction of a welded joint using ANSYS?

Submitted by khubaib1987 on

i got three questions here.

1) If im using ANSYS, how am i gonna do a fatigue life prediction of a welded joint? The speciment is butt joint. I need to know the procedure.

2) If im using ANSYS nCode DesignLife, how am i gonna obtain the SN curve if im using FE Model or Multi-column?

3) If Im using ANSYS nCode DesignLife, what should i pick for the geometry if im doing on CTOD method of a butt joint welded speciment?

Thanks for the help. :)

How to use cohesive zone modeling (CZM) approach in ANSYS?

Submitted by riyadmohammad on

Dear All,

Greetings to you. I am M. Faisal Riyad from Bangladesh. I am going to assist one of my professor in his research. The research will about crack propagation analysis. He asked me to learn about the cohesive zone modelling approach in ANSYS. I am searching for some good articles to learn from the beginning. I would be very grateful to you if anyone help me to find the articles or any other way to learn about cohesize zone approach in ANSYS.

 

Thanks,

Faisal 

Looking for a Great Solid Mechanics Book w/Solutions

Submitted by zaphead on

Dear all, I am an ME PhD graduate looking for a great classical solid mechanics text (preferably something that includes a thorough treatment of classical methods as well as finite deformation and an intro into computational methods). Here's the catch:

It's got to have good homework problems at the end of each chapter, AND a solution manual to those problems.  I really like the texts by Fung and Goldstein, however I can't find solution manuals to the homework problems.

 Can anyone suggest a book and its accompanying solution manual?

Post-Processing Software for LSTC LS-DYNA

Dear friends,

 

I am using LS-Dyna for my master's thesis. I am now using 'LS-Prepost 3.1' for my post processing. I am doing explicit time integration based contact modelling. Is Prepost is the best post processing tool for such modelling or is there any other better software. Of course Prepost is free, but i wanna know if there is any other free and more powerful post processor.

Finding a PhD position of 2012 Fall about Materials

Submitted by Yongjie WANG on

Being a undergraduate student of Harbin Institute of Technology,China, I will get my bachelor degree in JUL 2012 majoring in Composite Materials and Engineering. Then I want to find an availible PhD position of 2012 FALL to further my study.

I have studied all the basic courses of materials and mechanics in my bachelor education. Also I have got good scores in both class and lab. And you can see details in my CV and PS attached. 

Nonlinear Material Model using ANSYS

Submitted by riteshparikh on
I am performing the static analysis on hydraulics component where I am using the nonlinear material properties with multilinear kinematic material model having yield ~150 ksi and ultimate strength ~210 ksi. However I am getting first principal stress as 280 ksi and von Mises(equivalent) stress ~ 240 ksi.

I checked for the directional stresses where I find the stress in axial direction as ~279 ksi.

Whether it is possible to have the stresses above the given material limit (in this case true ultimate strength is 210 ksi).
