Sheet metal hardening curve determined by laminated sample and its adaptability to sheet forming processes
摘要
Abstract
The hardening curve for sheet metal can be determined from the load-displacement curve of tensilespecimen with rectangular cross-section. Therefore, uniaxial compression test on cylinder specimen made from laminated sample is put forward. Considering the influence of anisotropy on hardening properties and the stress state in popular forming process, plane strain compression test on cubic specimen made from laminated sample was advanced. Results show that the deformation range of hardening curves obtained from the presented methods is wide, which meets the need for the application in sheet metal forming processes. In view of the characteristics of methods presented in the paper and the stress strain state of various forming processes, the adaptability of the two methods presented in this paper is given.关键词
