Summary: | The effect of structural porosity on the elastic properties of sintered
materials was studied using the new multi-pore unit cell numerical model -
MPUC. Comparison between proposed MPUC model and previously adopted
two-phase unit cell - FCC numerical model as well as available experimental
data in literature, was done by comparing obtained values for modulus of
elasticity - E, shear modulus - G and Bulk modulus - K. Results obtained by
proposed MPUC model are in excellent agreement with available experimental
data in literature. It was confirmed that material porosity regarding pores’
size (volume fraction) has noticeable influence on elastic properties of
sintered material. Less porosity in the material microstructure generally
leads to noticeable higher values of E, G and K. For fixed volume fraction,
shape of pores has no significant influence on elastic characteristics. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. III
