Formability is the ability of a material to deform without fracturing, and the assessment of this property depends on various factors such as temperature, deformation speed, and stress state. There are two main approaches to determining formability: one is based on testing different materials under controlled stress conditions, and the other on developing failure criteria that depend on stress, deformation, deformation speed, and temperature. Bending of materials induces different stresses on the inner and outer sides of the sheet, which can lead to the Bauschinger effect during re-bending. Although the sheet formability test is outdated, it is still used to illustrate the properties of materials like high-strength steels. In this study, SolidWorks software was used to analyze the formability of the sheet during bending in a V-die, using different sheet thickness and materials.
