Shell to solid coupling is a feature of Abaqus software which enable us to run a model which some parts of it are shells while other region is solid. In this video you can find out:
What is shell to solid coupling?
How to apply shell to solid coupling in Abaqus?
How can we draw complicated parts by revolution feature?
How can we use rigid body constrain to apply concentrated moment to a deformable part?
How can we model a tube by conventional shell in Abaqus software?
This problem was also solved by shell to solid submodeling in the following videos:
