A Study of Single Point Incremental Forming by Finite Element Analysis

Abstract

The Single Point Incremental Forming Process (SPIF) involves extensive plastic deformation. The description of the process is more complicated by highly nonlinear boundary conditions, namely contact and frictional effects have been accomplished. The SPIF analysis is mathematically complex. However, due to the complex nature of these models, numerical approaches dominated by the FEA are now in widespread use. The paper presents the data and main results of a study on SPIF through FEA, that permits the modeling of complex geometries, boundary conditions and material behavior. SPIF have been studied under certain process conditions referring to the test workpiece, tool, etc., using ANSYS 11.0. An important result is showing that the model of simulation can give as clearly the behavior of contact tool - workpiece and the effect it on strain and stress distributions, also on the accuracy of product. Relevant dependences between tool and workpiece surface interface and sample of results have been demonstrated.
