I guess I know how to descretize and further processing but how can I make or define my sample for example(tensile sample) in fortran. 

Hi all,

I am trying to model an impact event but need to find out: 

• Long. Tensile Fracture energy
• Long. Compressive Fracture Energy
• Transverse  Tensile Fracture Energy
• Transverse Compressive Fracture Energy
  

 for a Glass/epoxy UD laminate.

Anyone please tell me the mathematical formulatation of Single ply thin composite plate with squre cutout.

I want to do buckling analysis of that composite plate using that mathematical formulatation.

Hi

I'm Jamal Mostafavi. I want to have some research about Xfem Method.I Read Prof  TED BELYTSCHKO paper with title of "A FINITE ELEMENT METHOD FOR CRACK

GROWTH WITHOUT REMESHING". I have a quastion about this papar:

 In eauation (9), He used General eqation of finite element. 

 uh = sum(u(i)*phi(i))

i from 1 to 10

 phi is  bilinear shape function

I want to do Phd in CFD or FEA.Can you suggest some phd topic. thanks.
