    What's the right connector

    Thanks FEA way, Yes it is, because I don't have a general pattern of fasteners, I need to place nails in specific positions and have them interacting with the holed plate, as the last step of these analyses would be to have the plate to be split in two, as happens during some tests. I need each...

    What's the right connector

    Thanks both of you! FEA way: The problem is a real life one: I'm trying to model a nail connecting a steel plate and a piece of wood, the two elements are detached at the moment because I just want to be sure of the connector behavior right now. When we test these specimens, we test their...

    What's the right connector

    Hello, I’m struggling trying to model a connector. What I want is to give it specific elastic-plastic behaviors in the three motion directions regardless the rotations, so that if one end point is moved away from the other in direction 1, the connector activates its “1” elastic-plastic...

    Problems with connectors

    I partitioned the plate in order to highlight the center, than I selected that point. What I don't understand is that CARTESIAN connectors shouldn't mess with rotations, only with displacements. Rotations are not settable DOFs, so, in my mind, the connector should work as a BUSHING with rigid...

    Problems with connectors

    retired13: Thank you! FEA way: Thank you for the hint. The CARTESIAN connector works fine, I think I tried only the BUSHING in the point-to-point configuration with the ENCASTRE, I thoiught I tried both. When I try the CARTESIAN in the plate-to-plate configuration, the reaction force in the X...

    Problems with connectors

    It isn't a structural or engineering design problem, it is a matter of the way I'm using (improperly) a tool in a specific FEA software, Abaqus. In the second line of the first post it is written “I need to model nails with a connector having three different elastic-plastic behavior in the...

    Problems with connectors

    Really sorry guys, my bad. I'm working on Abaqus CAE. I thought I posted on the abaqus related forum, I didn't.

    Problems with connectors

    Hi everyone, new here and I hope this isn't the same question over and over again, sorry in advance. I'm having problems with connectors, specifically finding one meeting my needs: I need to model nails with a connector having three different elastic-plastic behavior in the three different...
