The effect of wall thickness distribution on mechanical reliability and strength in unidirectional porous ceramics

open access: yesScience and Technology of Advanced Materials, 2016
Macroporous ceramics exhibit an intrinsic strength variability caused by the random distribution of defects in their structure. However, the precise role of microstructural features, other than pore volume, on reliability is still unknown.
