Hello All,
I need to model a Style 38 Dresser Rand coupling for one of my stress calculation.Is there anyone who can help me in this regard ?

Vrind,
Can you please provide the complete information!!
To the extend I know this type of coupling are of mechanical coupling. These are used in water services (what I used).
Generally this mechanical type of coupling will produce only hoop/longitudinal failure, since the cut grooving will only take out 1/3 of the total pipe wall thickness (compared to the threading)
So I don’t think you need any special consideration for modelling this in Caesar-II. Yes but do mention the coupling details as required to vendor.
I hope my assumptions are in line with what you need.
