Springback is an unavoidable problem in cold-forming processes and affects the efficiency quality of processing outer sheets for ships. Therefore, effective control prediction sheet-forming springback particularly important field cold-bending processes. To this end, paper presents research on based a study multipoint process combined with intelligent algorithms, as well production ship-hull pla...

Predicting the springback angle has become major production problem among tube benders. Springback is where on a mandrel-less rotary draw bending tends to bounce back after being bent when clamps are released. Accurately predicting crucial for effective bending. Machine learning (ML), popular prediction approach, was applied functions such as or function approximation, pattern classification, c...

The Swift test was originally proposed as a formability test to reproduce the conditions observed in deep drawing operations. This test consists on forming a cylindrical cup from a circular blank, using a flat bottom cylindrical punch and has been extensively studied using both analytical and numerical methods. This test can also be combined with the Demeri test, which consists in cutting a rin...
