    Model too stiff!!

    That I definitely want to do. But I can already tell you that also for the force-displacement relation my model will overestimate the reference stiffness of the paper's model by about a factor of two. This is, because I already use a model, that is either of equal length (in case the authors...

    Model too stiff!!

    Hey Erik, that I also tried, but here my model is also far too stiff. An additional difficulty that must be taken into account when considering the force-displacement graphs is the effect of probe length that directly affects the amount of force you need for a certain displacement of the bolt...

    Model too stiff!!

    Hey, the bolt bearing stress is computed using only the projected area of the bolt/laminate contact area. So you don't have to use pi times something but only bolt diameter times laminate thickness. That is just a general agreement within the "bolt bearing community" so to say. @ Erik: Thanks...

    Model too stiff!!

    Hey Erik, I know what you mean. But I think I already took care of this "symmetry condition" topic in a correct manner. When you look at the graphs illustrated in the paper you can see that they obviously relate to the full model, since a full model description is the only manner in which you...

    Model too stiff!!

    Hey everyone, I am currently trying to re-simulate some bolt bearing analyses described in a paper I found recently ( https://journals.sagepub.com/doi/abs/10.1177/0021998310391047 ). Unfortunately my model seems to be too stiff, approximately by a factor of 2, which I cannot explain up to date...

    Stop ABAQUS Standard Analysis with UAMP-Subroutine

    Hey, thanks a lot for your help, now it works!! :)

    Stop ABAQUS Standard Analysis with UAMP-Subroutine

    Hello everyone, I want to compress a cylinder until a certain reaction force is present in the reference point that is the bearing node for the cylinder. However, the termination of the computation is to be done by using the subroutine 'UAMP'. Unfortunately the computation wont stop and I...
