Summary

Finite element analysis results are compared to experimental results obtained during impact-excitation testing of a small ceramic beam. the experimental data were obtained by monitoring the transient vibration response of the beam using a non-contact pressure transducer (a microphone). Impact excitation was achieved by dropping a small metal sphere on the test beam. Making small cuts of various sizes using a metallurgical-sectioning saw simulated defects in the beam. the finite-element analysis data were reduced for comparison with the experimental data using a state-space model written in the software program Matlab®. Conclusions are made concerning the use of finite element models in precise modal analysis studies and the viability of the described experimental technique for the nondestructive evaluation of small ceramic components.
