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...

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...

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.

Just wondering if Window Vista platform is compatable with ANSYS V11.... Cheers.

Hi ya all, Please I need someone who is familiar with I-DEAS to assist. I am currently using I-DEAS for my composite FEA analysis, but I am having problem with my simulation. Firstly, I have problem in assigning a point load unto a surface. I tried using the node point loading technique but...

Hi ya all, Just wondering if any could help with information on best way to test for Shear modulus and Poisson ratios in composite. And is there a way one can use a FE method to test for this?,.. Cheers.

Hi ya, I am a new user to I-DEAS NX 12, and I am learning how to simulate composite analysis with it. Was wondering if any know of any available tutorials or cld help with information on how to apply laminates to FEA models in I-DEAS-NX 12...cheers.

Hi ya, Could any help with any information on how to calculate the forces acting on landing gear for large aircrafts and also how to size the Oleo (internal and external) and tires. Many thanks.

Hi ya All, Just wondering if anyone has come across any formula that enables you to size elevons or rudder appropraitely.Also, could any one help with formula to estimate landing field and range for space vehicle?. I wold be very grateful. Cheers.

Hi ya, I thought if anyone in here could be of help. I am currently having problems installing Ansys 10 (Multiphysics) with my Windows Xp (Home Edition). Whenever I try to install,it does half way and my computer shuts down completely.I have CATIA v5 installed on same computer, so I can't...

Hi ya, Can any one help with any formula ( if there is one) with which the estimation of a delta wing area can be calculated. The only parameter known is aircraft weight.

Hi ya, does any one know of any link to composite laminate database?. Many thanks.

Hi ya...Does any one knw of any equation to estimate the amount of propellant burn per height climb for a spcaecraft?..doing some spacecraft review. Cheers.

Hi ya, I am currently working on Anisotropic unsymmetric laminate beams. Could anyone help with where i could get good materials on calculating the Stiffness Matrix for such beam?. I am looking at performing FEA using Ansys or IDEAS with a beam made out of composite but Anisotropic and...

Hi ya All, This is my first post in this room eve though i have been reading post by others and the subsequent comments. I am currently looking for a good test book that contains information on how to estimate the mass of a space craft. I am currently working on a programm that involves space...

Hello, 'm abit new to this forum and I would be glad if some one would answer my question. I am doing some elastic stress analysis on composite beams, and I am new at this, I am not so sure of which failure criteria is best to apply. Personally I feel that Rankine and St. Venant(Maximum...

Hi all, I am new to this forum and i have found it very useful in so many ways. Just a qucik question on Ansys. I am currently looking at coupling of composite materials [Beam]. I am using Ansys Strutures as my FEA package but I am fairly new to the software. Does anyone know where i could get...

Hi ya, Does anyone know where i can get help in learning how to use Ansys FEA package to simulate elastic coupling in compsite?. I have this beam problem initially designed with metal but it being redesign with composite material and I am interested in looking at the coupling of the composite...
