Examples for Linear Gaps modelling.

ron.kunz
Dear all,
I would like to study some examples with linear gap elements. We don`t have SOL400 available and to have a work around for i.e. objects touching or near eachother.
Could you provide wtih some examples or give location of study material? Thanks.

    Hello Ken,
    Your last remark on this topic: "Choice of contact model (linear gaps or linear contact bodies) should not affect calculated bolt forces, assuming all other model details are the same. "
    Can you comment on the difference between linear contact and non-linear contact.
    The theory says this with SOL101:
    "SOL 101 contact or linear contact is, by nature, a nonlinear solution process. It requires solution iterations to satisfy both the equilibrium and contact conditions under certain tolerances. The user does not have to specify NLPARM card"
     
    With SOL101 does it really specify only initial contact and afterwards the shearforces are really transmitted true bolts (in case of bolts) and not through contact?
    Can someone explain me the difference between SOL400 and SOL101 for contacts if in both cases it is in fact non-linear?
     
    Thanks in advance.
