Finite Element Analysis on Compressive Property of a New Type of Porous Magnesium
新型多孔镁压缩性能的有限元分析

The bone tissue engineering scaffolds must possess good mechanical properties. Porous magnesium(Mg) metals have obvious advantages as a new class of bone tissue engineering scaffold. In this paper, the finite element method (FEM) was applied to systematically analyze the influences of porosity, pore size and pores arrangement on the compressive behavior of a new type of porous magnesium with straight pores fabricated by laser perforation technique. The distortion law of porous magnesium in the process of compression was also discussed. The results indicated that FEM can be an important way to the evaluation of mechanical behavior of this new class of porous magnesium metals and the application in bone tissue engineering.
