SHELL181 X and Y displacements

[Rodrigo Benitez]

Hi guys,

I'm studying a Cross-laminated timer plate under out-of-plane bending. I'm trying to obtain the X and Y (u and v) displacements through the thickness of the plate, stated by the ------- line in this picture:

The NODAL SOLUTION plot of U,X and U,Y give reasonable results:

Im trying to export the maximum and minimum values of, say, X displacement in the lateral central node to an ARRAY, but it seems that U,X and U,Y aren't available as ETABLE output. I alreay did this successfully to output U,Z and all the stresses, but when I try with U,X or U,Y, I get null results (0) in my array.

Any ideas? Is this possible or am I just deluding myself?

Thanks.

This is the code I'm using to GET the values into an array:

NSEL,S,NODE,,nolatu
*DIM,u,ARRAY,15
SHELL,BOT
j=1
*DO,i,1,15,3
LAYER,j
*GET,u(i),NODE,nolatu,U,X
j=j+1
*ENDDO
SHELL,MID
j=1
*DO,i,2,15,3
LAYER,j
*GET,u(i),NODE,nolatu,U,X
j=j+1
*ENDDO
SHELL,TOP
j=1
*DO,i,3,15,3
LAYER,j
*GET,u(i),NODE,nolatu,U,X
j=j+1
*ENDDO

It worked just fine with stresses and Uz.

Is value “nolatu” assigned anywhere? If it isn’t then obviously that would give you null values. Check the output window for messages.

You can also replace the *GET command with e.g.

u(i)=UX(nolatu)

UX() is a direct method via an enquiry function.
