Abstract
In the presented paper magnesium alloys wire drawing process for medicine application is investigated. The magnesium alloys has a low plasticity at room temperature and cold drawing process is difficult. That way, predicting of wire fracture is very important from theoretical and technological point of view. Analyzing of tensile test of magnesium alloys in micro and macro scale using results from 10000N Tensile/Compression Stage for the SEM, allow understanding a numerical model of fracture phenomena. The purpose of paper is to develop a mathematical models of flow stress and damage phenomena for magnesium alloys and implementation those models to FEM code.
