Abstract

Comparative analysis of the mechanical behavior of compact and porous beams operating under a bending regime is described. Experimental procedures are suggested for determining the different normalized parameters that characterize the mechanical behavior of porous and compact beams. The effect of pore space structure characterized by parameters m (the ratio of pore-former material and powder particle sizes) and ϑ (pore volume fraction) on the characteristics studied in this work for highly porous materials prepared by introducing a pore-former is analyzed.
