螺栓接触间隙的设置

zjl19850809

我在做螺栓和板的接触间隙时候，在加载前将单元的最大间隙设置为零了，发现这很难收敛，这是怎么回事，是不是应该有一点渗透，好保证收敛那？！！！！

Have you tried setting the contact and target suface penetrative?
I don't think penetrative is the answer. There are many factors, such as the density of mesh, load step and substep setting, contact parameter setting and so on.
First, check if your contact direction is right, and if your mesh is OK, and makesure your first substep is small enough.
Second, try changing contact parameters. usually, they  needn't any changes.
