education

After many years of teaching elementary mechanics and being unhappy with the high price of existing texts and their tendency to lead students into a game of pattern matching as opposed to thinking about fundamentals, I decided to assemble my lectures into a book.  So if you are looking for something different and concise on this topic you may wish to have a look at this book.  The book is also well suited for use as a refresher due to its brevity.

Where do i get tutorials with step by step procedure on abaqus. I need to solve a beam problem using composite layups with 3D elements

Hello!

I am
working on my master project, regarding post buckling of laminates with
piezoelectric layers.

Hi,

I am working on my post grads project, i would be very thankful if anyone does needful in this regard.

I need some suggestions in deriving out the non-linear governing  equation for a simply supported flat rectangular laminated plate , here i considered a uniformly distributed load. 

I have taken Von-Karman strains e(xx), e(yy), e(xy) with non-linear terms for a single term,

to derive the equilibrium equations of motion, is virtual principles of work or displacement necessary? 

Hi,



I am Sri Harsha from IITMadras.



I have been trying to do composite with 40 plies out of which 20 taper plies in 1 in 20 ramp.



It is giving error which I am sending in the attachment..



If
I am trying to work with 20 normal plies with no taper plies in it and only 20 taper plies separately
it is working but when I do combine these two it is giving error. I do not
know what was wrong in it. Can anyone please help me out in this. I have
to do this as soon as possible.
