Ship bending
WebJul 13, 2024 · A ship’s hull is basically made up of bent plates welded together. If these plates are not stiffened, the bending moments on the plates due to the loads may exceed the value of stress that can be withstood by the material, and hence cause failure. So, the plates are stiffened (or their section modulus is increased) by adding stiffeners to them. WebFeb 19, 2024 · The hull of a ship is the most notable structural entity of the ship. To define the hull, it can be said that it is the watertight enclosure of the ship, which protects the cargo, machinery, and accommodation …

WebFeb 6, 2024 · I was in the process of throwing out the table mount when I noticed a few parts that may be useful for plank bending. Turns out it was a simple matter of fitting them to the iron. The double taper part has female threads so attaching it to the iron was simple using a screw. See photos. The bigger drum works well but takes about 30’ to heat up.
