Description
This paper considers the development of a mathematical model for drawing MgCa08 wire with an option for fracture phenomena prediction in micro scale. The first part focuses on experimental studies that include upsetting and tensile tests and metallographic analysis of material for a micro scale fracture model. The second part examines development of a multi-scale numerical model of fracture phenomena. It also describes a computer program developed to enable the prognoses and observation of discontinuity in grains boundaries during deformation.
