This paper describes and compares five types of catalytic structures devised for automotive honeycomb catalytic converters, all of whose honeycomb meshes vary in shape - regular triangle, regular hexagon, square, and corrugations (types A and B).
Each honeycomb structure is analyzed as a two-dimensional frame structure, and its thermal deformation and thermal stress are discussed in comparison with those of the other types.
The analytical results are examined for differences in mechanical properties, the effects of the outer cover and of the wire mesh support, the development of cracks, etc.
Further, through the use of simple experimental models, the paper describes how the analytical results have been proven to be correct.
