Magnesium and Magnesium alloys have attracted immense attention as a biomedical implant material due to favourable mechanical properties and biocompatibility. Biodegradable nature of Magnesium dismisses the need of revision surgery for removal of implant. Porous Mg- foams are advantageous as presence of pores allows the higher degree of osseointegration. The mechanical properties of the porous foam material is a function of its density, thus a Finite Element Method (FEM) approach is required to predict the behaviour of Mg- foam under various stresses for real-time application. The author has attempted to quantitatively assess the mechanical properties of Mg foam with a 40-45% porosity with 100-300 μm pore size. The deformation behaviour of Mg- foams with different porosity under the compressive and bending loads has been described by “Deshpande and Fleck model” with ABAQUS FEM software. The simulation results have been compared with the recent publications. An agreeable comparison has been seen in the results.
