Sentence examples for main damage modes from inspiring English sources
In CAI test, wrinkling of facesheet and buckling of foam and skin are the two main damage modes.
In this study, a multi-scale computational approach was developed and the 3D Hashin damage criteria were applied to capture main damage modes of a braided textile composite.
Here, a multi-scale computational approach was explored to capture main damage modes of a braided textile composite; simulations were supported by experimental verification.
The main damage modes are matrix cracking for lower impact energies, delamination and fiber breakage for middle impact energies and complete breakage for higher impact energies.
The numerical results showed that the main damage modes of FBCR3DW were matrix damage, yarn transverse damage and yarn longitudinal breakage, which were in good agreement with the experimental findings.
From the visual inspection, for the impacted side of the samples, it is noted that the main damage modes for repaired samples are matrix and fiber cracks around point of impact and delaminations while severe matrix cracks expanded through fiber directions are the dominant damage mode for unrepaired samples.
For the thick asphalt pavement structure, the main damage mode is of the "bottom-up cracking" type, whereas "interface cracking" damage is typically displayed for flexible pavements.
In this example, the impact energy of 7.35 J was selected to simulate the damage evolution process in the cross-ply laminate since 90° matrix cracking was the main damage mode expected with crack induced delamination (the impact energy is too low to cause fibre breakage).
The main damage and failure modes and their interaction of braid yarn are provided as well.
Then, the analysis and the observation of Acoustic Emission (AE) signals led to the identification of the main acoustic signatures of different damage modes dominant in each type of composite materials (laminates and sandwich).
Microscopy analysis of impacted region revealed that debonding, radial cracks, transfer cracks and delamination damage modes are the main observed damage modes.
