- Abstract
The dynamic Young’s modulus of porous titanium and Ti6Al4V with various porosities was measured using the electromagnetic acoustic resonance method. The dependence of Young’s modulus ( E) on the porosity ( P) has been analysed in detail based on Phani–Niyogi relation $$ \left(E = E_0 \left(1 - \frac{P} {{P_C }}\right)^n\right ) $$ and Pabst–Gregorová relation $$ \left(E = E_0 (1 - aP)\left(1 - \frac{P} {{P_C }}\right)\right) $$ . We find that both Phani–Niyogi relation and Pabst–Gregorová relation with fixed material constant n = 2 or a = 1 but varying P C can correctly account for the dependence of Young’s modulus on the porosity for porous titanium and Ti6Al4V.
