Mechanical Properties of Ti-6Al-4V Octahedral Porous Material Unit Formed by Selective Laser Melting

Abstract EN

The Ti-6Al-4V octahedral porous material unit is designed to calculate its load.

In this paper, ANSYS is adopted for the load simulation of the unit.

And a simplified model of dimensional theoretical calculation is established, by which the analytical equation of the fracture load is obtained and the calculation of the load of Ti-6Al-4V is completed.

Moreover, selective laser melting is adopted in processing the Ti-6Al-4V porous material unit.

The experimental value of fracture load of this material is obtained through compression experiment.

The results show that the simulation curves approximate the variation tendency of the elastic deformation of the compression curves; the curves of theoretical calculation approximate the general variation tendency; and the experimental value of fracture load is very close to the theoretical value.

Therefore, the theoretical prediction accuracy of fracture load is high, which lays the foundation for the mechanical properties of the octahedral porous material.
