Simple electrical resistance measurements can be utilized to extract this information about physical integrity from the material. Smart behavior was evaluated by performing unconfined compression tests on cylindrical carbon fiber-reinforced mortar specimens. The signal that was manifested was a reversible change in resistance when cracking was not significant (for example, when stress-strain response was still elastic), and an irreversible increase in resistance when cracking took place. Smart material capability existed even at low fiber volume contents (0.2% to 1.0%).
