Cake molds

A rocket consists of thin-walled shells, and while bolts can be used to fasten them, it has its drawbacks such as high contact stresses, requiring reinforcement plates, overdesigned bolts, weakening of shells, and increased error in strength calculations. An alternative method is creating interface elements by deforming the edges of the shells, similar to cake molds nested inside each other. This connection can be done in two ways: automatically disconnecting when the spacecraft's engine is turned on or providing tabs that snap, making it non-separable. However, some proposals may not fully adhere to the conditions, but they should not limit the scope of finding the best solutions excessively. In an exaggerated example, a rocket body made from a single piece of oak with dried snake skins lined and fixed using bronze studs is provided, but such restrictions should not lead to exclaiming "What the hell snake skins?!" instead of submissively accepting terms.
