I'm trying to simulate a steel/acrylic pressure hull design for asubmarine - the joint between them needs to allow the acrylic toshrink at a higher rate than the steel- the steel hemisphere has aflange angled in that the acrylic hemisphere sits in, to allow itto slide inwards as it compress.

Does anyone know how to simulate a joint like this? Cosmosautomatically thinks they are stuck together at the joint, whichcauses way more stress on the steel flange and deforms the acrylicto a bell-shape, which is way different from the way it would bestressed in a dynamic joint.

Is there a way to define a joint like this in CosmosWorks? Icouldn't think of where an option might be- Maybe in the way themesh is defined around the joint? Does anyone have experience withthis?


Any help is very much appreciated.SolidworksSimulation
