Abaqus has a room for coupled thermal-displacement analysis which u can then feed into your dynamic analysis using Abaqus "restart" capability.

Do you have a pictorial representation of what you are trying to model and I may be able to help out. As Corus already mentioned, its not a coupled thermal-displacement problem unless there is an external force system acting somewhere alongside a change in temperature ( i.e thermal...

you have to be very careful using direct normal or tangential forces calculated by Abaqus in any contact analysis. you need to understand fully how abaqus simulates contacts and how it derives forces for each given contact formulation abaqus uses. Barely ticking CFN in the Field output doesnot...

To Gbor, Sorry I didn't intend to say you were advertizing the software..Just thought user interactivity was fully thought when the software was being created. I would be keen to try it out and see how it benchmarks some of the other known FE softwares. Put it simple, the concept of 3-2-1 is...

You have to make sure you are in the Part module when you seed your edge or surface area during mesh refinement in Abaqus.

Ok, good link..thought the roshaz software was pretty impressive... althought looks like its only a pre and post precessor with no independent solver. The example in the movie clip with the 3-2-1 constraint abit misleading. Higher stresses occuring at the node positions where the body was...

Does a 3-2-1 constraint approach really makes much difference in a Non-Linear analysis. Also, from mathematical point of view, what other benefit does it provide in linear static analysis apart from the widely aclaimed balance of global forces and does it mtter which plane the contraints...

Thanks rb1957, I completely understand that, however does it actually make much difference to the stresses acting(in reality) considering that the grease holes are quite small. Also, do you need to account for Kt effect given that the hole is somewhat a stress feature in itself. Regards.

I would be very much appreciative if anyone could assist with reference material on analysis of Pins with greased holes. I know Bhrun did touched on the topic but not in great details. I am particularly concerned about the effect of the grease holes on the section modulus of the Pin in bending...

Badri07, Depends on which fatigue analysis you are trying to teach yourself. There's classical fatigue analysis and there's also FE fatigue analysis. As a beginer you would need a very good grounding in theorectical fatigue analysis. I would recommend :Fatigue of Structures and Materials by...

Thank you Guys for your valid contributions and assistance...very much appreciated. Sharpedge

thanks all for contributions ..much appreciated. Regards.

Thanks ....could you recommend any good textbook that covers analytical stress analysis covering pressure vessels, fatigue damage and failure analysis, unsymmetrical bending and inelastic buckling..

Hi ya all, Just wondering if any one could help with a very good stress analysis text book that covers in detail analytical stress analysis techniques as well as some basic FEA. I currently have T.G Megson's book but just wanted to know if there are other books much better than megson's book...

Just wondering if any knows if MSc Patran is compatible with Windows vista. looking to purchase a copy but I am not sure if it is compatibile with vista.
