Flexural Properties and Fracture Behavior of Nanoporous Alumina film by Three-Point Bending Test.

This study investigated the influence of porosity on the flexural property of a nanoporous alumina film. When the porosity of the alumina film increased, both bending strength and modulus declined. The results from the bending test revealed that the setting of the film during the bending test had significant influence on the flexural property.
