Finite element simulation of twist forming process to study twist springback pattern
Springback is one of the most common defects found in the metal forming of automotive parts. There are three conditions which can be considered as springback i.e. flange angle change, sidewall curl and twist springback and among them, twist springback is the most complicated problem. This study...

description |
Springback is one of the most common defects found in the
metal forming of automotive parts. There are three conditions which can
be considered as springback i.e. flange angle change, sidewall curl and
twist springback and among them, twist springback is the most
complicated problem. This study will focuses on the development of finite
element simulation model of the twist forming process. The main aim of
this project is to investigate the parameters that may affect the twist
springback. Few parameters including twist angle, hardening constant and
thickness are explored using finite element (FE) software ANSYS
Workbench (16.0). The rectangular mild strips are used to form the twist
forming. The standard material properties and stress-strain curve of mild
steel had been used to get the springback prediction. The results of
springback were measured by the difference of the bending angles before
and after unloading process. The results were then be validated with the
research made of Dwivedi et al., (2002). The results show that the
springback angle reduces as the thickness of strips are increased and also
as the angle of twist increases. |
