SPECIAL FINITE ELEMENT-BASED UNIT CELL APPROACH FOR THE PREDICTION OF MECHANICAL PROPERTIES OF FOAMED TITANIUM

摘要：

With superior mechanical and biological properties,titanium-based foams have potentially beneficial applications for bone-replacement implants in biomedical engineering.To predict microscopic stress and strain localizations (as well as macroscopic responses),finite element (FE) analyses can obtain full-field solutions for better understanding of the relationship between pore morphology,overall properties and strain localization In this study,a simple two-dimensional unit cell approach (UCA) is developed based on micromechanics and special finite element method for multiscale modelling.Initially we have predicted the elastic mechanical properties for foamed titanium with a reasonably accurate depiction of the actual geometry of the microstructure.
