Hi, I am new to abaqus.I want to know that how can i find E22. I have a unit cell of fiber reinforced composite and model is a cube and i applied displacement boundary conditions in u2 direction. I want to find Young,s modulus E22 for that i need to find sum of forces on all nodes on unit cell...

Dear Rob, Please if you get some time then have a look on my problem. I shall be very greatfull to you for this kindness. Best Regards Ali

Dear Rob, Thanks a lot this really helped me much. It works very fine when i have to make Plane Z =0 and Plane Z=L planer.But i am getting problem when i have to make plane X=0 and Plane X=L planer. For this case i am applying following boundary conditions Plane u1 u2 u3 ur1...

Dear rstupplebeen thanks for your reply, I have attached the input file. Because I have two materials in composit and both have different stiffness so dont get equal deformation but i want that palne should remain plane. The problem i am facing for plane remain plane case is that i cant apply...

I have to find out the shear modulus from a 3D cube unit cell of composit and for that I want to made two models 1- By applying homoganeous boundary conditions (faces remain palne) 2_ By applying Periodic boundary conditions, in this case opposit faces should have similar deformation, so that...

Hi All, I am working on a unit cell of a composite and model is a 3D cube. Because its a small part of a very big part so i need to apply PBC. I know its possible with *Equation,,,, i am trying to write it in inpit file.FOr that I created node sets of all six faces of unit cell.and now have to...

I am making two surfaces(in X Planes) of a cube rigid, and its a 3D problem. While edge nodes of those two surfaces are shared with other surfaces(in planes Y and Z)which have boundary conditions. So i get warning of inactive degrees of freedom

ya i am making two surfaces of an object rigid

Hi Dear All, My Model is a cube,working in Standard CAE, element type is C3D20R and i have to find out shear modulus. For that i am applying displacement BC on Z=L plane in U11 direction.BC are as follows Plane X Y Z Z=L .002 0 0 Z=0...

Hi Corus, I am applying tie constrain on two surfaces of my cube, but i am getting these warning, Would you please help me why i am getting these warnings For *tie pair (assembly__pickedsurf264-assembly__pickedsurf263), adjustment was specified but no node was adjusted more than the adjustment...

Corus thanks for your help I applied equation and it worked

Thanks Tata for your reply Ya i got same warning, but i want to apply both conditions on all nodes. I am working on composite, i have a cubic block and i applied displacement Bc in +U1 direction and also applied BC in -U1 direction as u1=0. Now fiber and resin deforms differently because they...

Hi, I am Ali and new to abaqus.I want to know that is it possible to apply coupling and boundary conditions together on the same nodes? I want to apply kinematic coupling on four surfaces of a cube and boundary conditions on rest of two surfaces. Please help me out. Thanks in advance
