DEVELOPMENT OF A MATERIAL CARD FOR NUMERICAL SIMULATIONS OF SHEET METAL FORMING
Original language description
The article addresses the development of a material card for the numerical simulation of sheet metal forming. It elucidates the fundamental principles of digital image correlation, which will be employed to assess the measured data. The yield criterion Vegter 2017 was selected for the material card's characterization. Consequently, the experimental segment encompasses two distinct types of measurement. The initial measurement entails the tensile test, adhering to EN ISO 6892-1. The outcomes from the tensile tests furnish the hardening curves, essential mechanical properties, the strain hardening exponent (n-value), and the Lankford coefficient (r-value). The subsequent measurement involves the Nakajima test, conforming to EN ISO 12004-2, to derive the forming limit curves (FLC). The ARAMIS optical system by GOM was utilized for deformation measurement and material property evaluation. The objective of the experimental component was to acquire data at varying loading rates and subsequently employ these to formulate a material card within the AutoForm software, which is applied for numerical simulations of sheet metal forming.
