Good evening Dear colleagues,
This is a cyclic test of a metallic brace surrounded by a box of concrete. The brace resists axial loads (tension and compression), and its concrete role is to prevent this brace from buckling in the case of compression. There is a gap of 1 mm between the brace and...
it's was a problem of contact, but I didn't create general contact, I just checked the box of the adjustment and prevented overclosures between slave and master surfaces in the interaction between the core and the restaining, so after that, I didn't get any penetration anymore.
but I have a...
Yes its core with auxetic structure, I try with another mesh, this time all the parts using wedge elements with 15 mm but the problem doesn't change ,every time with this penetration don't know why ?! As shown in the curve ,model start buckle after few cyclic loadings.
Yeah I think it's problem of meshing ,but it's hard to mesh the core part because of the re_entrant honeycomb holes and especially those sharp angles ,the core part need a pro mesh can't find the appropriate one I try with hex but failed even with partitions, whats your suggestion for meshing...
Hello,
I have some problems with my Abaqus model, the job ran successfully and complete the time but the result is not as desired, the model shows a deformable shape and the hysteresis curve failed to get symmetrical loops.
the model is a metallic damper under cyclic loading.
step= static...
