1. An apparatus for evaluating the radial compressive strength of a ceramic honeycomb sample, comprising:
a housing defining a testing compartment;
a pressure subsystem configured to introduce a pressurizing fluid into the testing compartment;
a flexible member disposed within the testing compartment and in fluid communication with the pressure subsystem, the flexible member defining a testing area within the testing compartment configured to receive the ceramic honeycomb sample, wherein the flexible member is configured to expand inwardly and subject 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 covering an end face of the ceramic honeycomb sample when the ceramic honeycomb sample is positioned in the testing compartment; and
an acoustic sensor disposed on the end cap and configured to translate acoustic waveforms propagating through the acoustic sensor to a signal representative of the acoustic waveforms,
wherein the acoustic sensor is engaged with a waveguide defined by the end cap.
