The multi-scale physical and numerical modeling of fracture phenomena in the MgCa0.8 alloy

The MgCa0.8 alloy can be used to produce surgical threads. However, the low plasticity of this alloy causes problems during wire drawing. A numerical model of the drawing process can be used to optimize the deformation parameters. Research has shown that fractures in MgCa0.8 start within grain boundaries; therefore, a model of the drawing process should consider this mechanism. The main purpose of this work is to develop a micro-scale numerical model of fracture in MgCa0.8 using the boundary element method (BEM). Additionally, the potential for using the developed BEM model as a part of the multi-scale model of the drawing process is investigated.
