Abstract: An apparatus and methods for evaluating the radial compressive strength of ceramic honeycomb samples. The apparatus includes a housing defining a testing compartment. A pressure subsystem is configured to introduce a pressurizing fluid into the testing compartment. A flexible member is in fluid communication with the pressure subsystem. The flexible member defines a testing area within the testing compartment configured to receive the ceramic honeycomb sample. The flexible member expands inwardly and subjects the honeycomb sample to a compressive force by engaging against the outer surface of the honeycomb sample when pressurized by the pressurizing fluid. An end cap covers an end face of the ceramic honeycomb sample when the ceramic honeycomb sample is positioned in the testing compartment. An acoustic sensor disposed on the end cap is configured to translate acoustic waveforms propagating through the acoustic sensor to a signal representative of the acoustic waveforms.

Abstract: A honeycomb body having a honeycomb structure and a peripheral skin, the honeycomb structure having walls defining a plurality of cells including peripheral cells disposed directly adjacent to the peripheral skin. One or more of the peripheral cells is at least partially defined by a first wall surface, a second wall surface, and a skin surface portion extending between the first wall surface and the second wall surface. A continuously-varying radius extends from a first tangent to the first wall surface along the skin surface portion and to a second tangent to the second wall surface. Other honeycomb bodies, structures, and extrusion dies for forming honeycomb structures are disclosed.

Abstract: A method and system for inspecting a honeycomb body. The method includes capturing a first image. Instances of at least one feature in the first image that correlates to a structural characteristic of the honeycomb body are detected. One or more detected instances of the at least one feature identified in the first image are abstracted by creating a graphical representation of each of the one or more detected instances of the at least one feature. A second image is generated by augmenting the first image with the graphical representation in place of or in addition to each of the one or more detected instances of the at least one feature identified in the first image. The second image is analyzed using a machine learning algorithm to classify the honeycomb body with respect to the structural characteristic of the honeycomb body.

Abstract: A non-contact method of characterizing the isostatic strength of a ceramic member or article includes capturing a digital image of the ceramic article, and then forming a two-dimensional representation of the ceramic article and the web therein based on the captured digital image. The method also includes performing finite-element analysis on the two-dimensional representation of the ceramic article using a select amount of simulated isostatic pressure to determine a maximum stress value within the two-dimensional representation of the web. The method further includes using the maximum stress value to characterize the isostatic strength of the ceramic article.
