Material property of a solid body measuring as proportionality coefficient between tensile stress \sigma (force per unit area) and axial strain \epsilon(proportional deformation) in the linear elastic region of a material:
| (1) | E = \frac{\sigma}{\epsilon} |
Young modulus depends on porosity as:
where
E_0
\phi usually
\phi \in 0 \div 0.4
\phi_c usually
\phi_c \approx 1
f characteristic exponent usually
f \in 1.1 \div 1.7
(2)
E = E_0 \cdot \left( 1- \frac{\phi}{\phi_c} \right)^f
Young modulus of solid material porosity critical porosity
