Abstract
Thermal shock resistance of a ceramic honeycomb structure is increased through modifications of the cell wall joints. Wall joints can be modified such that a longitudinally-extending opening is created, putting two or more cells that meet at the wall joint in fluid communication through such opening. In such a case, all walls that meet at such a modified joint must join at least one other wall at that joint. Alternatively, wall joints can be modified by providing stress concentrating notches which extend into the joint from two or more cells that share the joint.
