Can you be more specific? Are you doing to do a linear FE stress analysis or a thermal FE analysis? 

What is the goal of the project? Using a Matlab FE code to analyse the tunnel?

Best regards,

Phu

Dear Phu

thank you for your answer

the goal of this project is to determine displacements and stresses. For making this project easier we assume it is rectangular tunnel in 2 dimensions. We must calculate elements by plan stress equations.

thank you morteza but I'm searching a sample tunnel modeling in matlab which I learn what should I do for modeling tunnel.

The best book is

F. Saleri

Dear Gabriel

thank you for your book but i don't know italian language, it doesn't have an english version?

The language i think is not a really problem because in matlab the commands is writed in english, in finally you have an arrangement google traslate. (I can't speak beautiful english but i use the google traslate for the word.)

thank you so much Gabriel

so does it have an tunnel project example?

best regards, Mohammad

Hi Mohammad,

I highly recommend you to use Rocsience Package especially Unwedge for your study. Actually Plaxis 2D also works for you. you can easily model the tunnel by both. If you are beginner in MATLAB, it takes too much time to do this.

Thank you so much Mehdi

I appreciate you too,because of your paper with Prof. Fakhimi, they are so interesting too.

This question is related to my Finite Element Course Project and I and all my classmates are beginner in matlab, because of that we are searching for Sample Tunnel Project...or a useful book in this road 

thanks

Hi Mohammad.

How can I contact you?

I want to ask you about tunnel modelling by Matlab.
