| heal.abstract | Materials subjected to alternating stresses exhibit temperature fluctuations indicative of damping. Temperature effects give rise to entropy production. An analysis is made to obtain the entropy produced for a vibration cycle. This corresponds to the reciprocity of temperature rise and strain yielded that alter the material damping factor as a function of shape and magnitude of material porosity. Prototype bars of pure aluminum oxide with different porosity are considered. They consist of uniformly distributed cavities and are subjected to alternating axial stress. Dynamic characteristics of the porous medium are determined to evaluate the damping factor of the tested bars. The experimental data correlate well with the analytical results. The damping factor measured and calculated in this work, can be used as an indicator of structural integrity. | en |
