Stretch forming is a process which involves tensile and bending forces during the operation.(a) True(b) FalseI have been asked this question in an interview for internship.I want to ask this question from Stretch Forming topic in chapter Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer»

Right choice is (a) True

The best explanation: In STRETCH forming process, stretching of a metal sheet is basically done by HOLDING its edges and bending it on a cylindrical block, simultaneously is known as stretch forming. This process basically INVOLVES tensile and bending FORCES during the operation. In this process, the materials with high ductility are mostly stretched by rigid dies.
