Damage monitoring in sandwich beams by modal parameter shifts: a comparative study of burst random and sine dwell vibration testing [PDF]

, 2010
This paper presents an experimental study on the effects of multi-site damage on the vibration response of honeycomb sandwich beams, damaged by two different ways i.e., impact damage and core-only damage simulating damage due to bird or stone impact or ...

Improved impact performance of marine sandwich panels using through-thickness reinforcement: Experimental results [PDF]

, 2010
This paper presents results from a test developed to simulate the water impact (slamming) loading of sandwich boat structures. A weighted elastomer ball is dropped from increasing heights onto rigidly supported panels until damage is detected. Results

Localization of transversal cracks in sandwich beams and evaluation of their severity [PDF]

, 2014
An algorithm to assess transversal cracks in composite structures based on natural frequency changes due to damage is proposed. The damage assessment is performed in two steps; first the crack location is found, and afterwards an evaluation of its ...

Performance of Pre-Stressed Sandwich Composites Subjected to Shock Wave Loading

EPJ Web of Conferences, 2010
The present paper experimentally studies the dynamic behaviour of prestressed sandwich composites under blast loading. The in-plane static compression loadings are implemented on the sandwich composites before they are subjected to the transverse ...

Fabrication and braiding angle effect on the improved interlaminar shear performances of 3D braided sandwich hybrid composites

Journal of Materials Research and Technology, 2023
While the interlaminar hybrid composites have been used widely and still remain in great demands, interlayer delamination, undesirable in most cases, keeps a common defect, due to the lack of interlaminar fiber-connection.
