An efficient spreading method for sheet metal parts based on outside normal

An efficient spreading method for sheet metal parts based on outside normal Purpose – The paper's purpose is to provide a new spreading method for sheet metal parts, which aims to improve the standard radial spreading method. Design/methodology/approach – A new radial spreading approach considering outside normal direction, which is based on geometric mapping method and triangle elements, is developed to resolve blank development in sheet metal forming. Findings – Through practical applications, the effectiveness and usefulness of the approach presented are evaluated, and the development result is more reasonable, meanwhile, the obtained blank shape should be a better initial values in the application of one‐step analysis for fast deep drawing simulation. Originality/value – This paper offers a more reasonable spreading method for sheet metal parts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Engineering Computations Emerald Publishing

Abstract

Purpose – The paper's purpose is to provide a new spreading method for sheet metal parts, which aims to improve the standard radial spreading method. Design/methodology/approach – A new radial spreading approach considering outside normal direction, which is based on geometric mapping method and triangle elements, is developed to resolve blank development in sheet metal forming. Findings – Through practical applications, the effectiveness and usefulness of the approach presented are evaluated, and the development result is more reasonable, meanwhile, the obtained blank shape should be a better initial values in the application of one‐step analysis for fast deep drawing simulation. Originality/value – This paper offers a more reasonable spreading method for sheet metal parts.
