Composite sandwich structures are well-suited for applications requiring high bending strength, flexural rigidity, crashworthiness, and light weight. However, skin–core debonding core failure remain a barrier to optimal structural performance when polymeric foams used as materials. Suppressing or compartmentalising these modes can enhance the integrity of structures. In this paper, response str...

Vibration of laminated composite and sandwich plate under thermal loading is studied in this paper. A refined higher order theory has been used for the purpose. In order to avoid stress oscillations observed in the implementation of a displacement based finite element, the stress field derived from temperature (initial strains) have been made consistent with total strain field. So far no study ...

The vibrational behavior of composite structures has been demonstrated as a useful feature for identifying debonding damage. precision the damage localization can be greatly improved by addition more measuring points. Therefore, full-field vibration measurements, such those obtained using high-speed digital image correlation (DIC) techniques, are particularly useful. In this study, deep learnin...
