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

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.
