No prestressing of the bolts. It is only a first model. I will think about that.
Harry has used "cooling" of rebars to simulate prestressing of concrete beams.
If you are using contact analysis already, one can simply achieve pretension (without *PRETENSION
) by design.
In this case you will have overlapping solids.
i.e. There is a gap between both plates (0,01 mm) and a "negative" gap between bolt's head and it's supporting plate (-0,3 mm)
ccx will solve this intrusion by applying as much strain as needed to accomplish the contact constraint.
So no heating up to melting point is needed.
And therefore no firefighter needs to be present, while you are doing your calculations
