The methodology being presented is an attempt to exemplify how a typical mechanical testing can be accompanied by easy to access, affordable pieces of equipment, but to reach a level of information substantially beyond somewhat standard practices. Fingerprints of discrete crack and damage formations during tensile testing are collected by a general purpose noise-reducing microphone in conjunction with a digital video microscope. Six cross-ply-like, specially orthotropic laminates, (0/905)s, (03/903)s, (05/90)s,(0/90)3s, (90/0)3s and(903/03)s are studied. Mechanical test results suggest that the current methodology is able to identify progressive failure events/regimes characterized by unique audio signal profiles. Access to Supplementary video and audio recordings are also provided to discuss and validate the efficiency and benefits of the proposed approach.
