Hello all,<\/p>\n

I am trying to replicate a double lap shear tensile test we did on a composite coupon to check for adhesive failure but I am having issues setting up the bonded interactions between the composite shell and adhesive body.<\/p>\n

I set my composite coupon as a surface and did a solid body for the adhesive, as shown below:

For my bonded interactions, I did this:

<\/p>\n

But the premilinary results I get show like if only 1 side of the composite surface is bonded:
<\/p>\n

I also tried to set the bonded interactions as 1 command, but I get the same results when I use a surface.<\/p>\n

Also, if I suppress the side that looks bonded and leave the other side as is, I get the same mirrored results.<\/p>\n

<\/p>\n

I believe is something related with the surfaces because I did the same test with solid bodies (no surfaces) and the premilinary results look more realistic:
<\/p>\n

Any ideas what I could be doing wrong?<\/p>\n","protected":false},"template":"","class_list":["post-369767","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
