TLDR
In this article, the authors developed a finite element (FE) model for analysis of punching process and validated it with experimental testing results by comparing burr height and found that FE result is -179% difference compared to experimental result.Abstract:
Punching process is an operation that a scrap is separated from a metal sheet by a punch Improper setting of punching conditions may lead to excessive of material deformation around edge region (burr), which may weakening the strength of produced part Analysis of punching mechanics would be beneficial reducing defective part One of effective analysing tool for this application is Finite Element (FE) method The aim of this study is to develop reliable FE model for analysis of punching process The FE model was developed based on 2D FE result was validated with experimental testing result by comparing burr height It was found that FE result is -179% difference compared to experimental result Good agreement between FE and experimental result was obtainedread more
