Hello, I'm attempting to simulate a steel pressure vessel with a notched defect and composite wrap repair. See the picture below.
I've meshed the assembly in using hex elements with shared topology between the parts. See the mesh below.
I'm trying to get the opening strain energy between the two materials at the notch interface. Basically, I'd like to see if there's a way to simulate the repair separating from the pressure vessel at this notched area. See below.
Right now, since the mesh has shared topology, I suspect there's only one node where the meshes of the two parts meet, which means they won't separate at all and will strain together no matter how much load is put in. Any thoughts on how to best simulate this problem are much appreciated!
