Cyclic Mechanical Load

This article presents an experimental investigation of repair of a crack in a structure using piezoelectric material under thermo-mechanical loading environment. The cyclic mechanical load is applied on a plate with a straight and angular crack under uniform temperature environment. Two cases have been considered for the repair of crack under (a) mechanical loading and (b) thermo-mechanical loading environment. A piezoelectric sensor is utilized to measure voltage. The measured voltage is used to calculate the stress intensity factor in passive and active modes. The effect of a single and double piezoelectric patch in the repair of the plate is investigated. The double piezoelectric patch is found to be more effective as compared to single patch when placed symmetrically offset from the crack. An optimal value of voltage and phase difference is evaluated for most effective crack repair. Location of the piezoelectric patch is varied with respect to crack location, and best-suited position for effective crack repair is proposed. The viability of piezoelectric used for repair under thermo-mechanical loading is discussed. The active mode of repair by piezoelectric is found to be effective under thermo-mechanical loading environment.

Cyclic Mechanical Load

In an effort to better understand the role of mechanical loading on the healing and remodeling of biological tissues, a number of in vitro models have been developed to apply either static or cyclic mechanical load to cell-seeded scaffolds (Huang 1993, Langelier 1999, Cacou 2000). The current study describes the validation of a new system designed to facilitate the study of matrix remodeling in cell seeded scaffolds, as well as the formation of tissue engineered scaffolds for potential use in repair of healing ligaments and tendons. Our objective was to develop a system that would allow a cell seeded scaffold to remain viable under cyclic loading for long periods of time, with the capability to apply complex loading regimes to the scaffold while monitoring the load in the scaffold.
