Optimized Design Method of the Prefabricated Hole for Flanging Forming of Square Tributary Junction on Spherical Shell

Optimized Design Method of the Prefabricated Hole for Flanging Forming of Square Tributary Junction on Spherical Shell

The key problem for flanging forming of square tributary junction on spherical shell is to determine the shape and sizes of prefabricated hole. In order to investigate precise shape and sizes of the prefabricated hole, an optimized design model was established. The flanging forming process was simul...
