Analysis of composite laminates with intra- and interlaminar damage

Matrix cracking in polymeric composites laminates: Modelling and experiments

“…Matrix cracking and its effect on material properties degradation has been investigated by many researchers, see, e.g., reviews [1][2][3][4][5]. In most cases the effort has been focussed on the development of a representative local stress distribution model between the cracks, which is then used to determine certain thermo-elastic constants.…”

Finite Element Study of Delaminations in Notched Composites

“…Previous papers [6,7] have pointed out the complexity of predicting interacting intralaminar and interlaminar damage growth. The finite element models are either conducted by implementing user-defined commands in finite element codes, or restricted to predefinition of possible failure regions.…”

Enhanced Composites Integrity Through Structural Health Monitoring

“…In addition, there are the numerous reflections and mode conversions at boundaries that can complicate the signals and signal analysis. Further research needs to be done to better understand the interaction of guided waves with damage in composite materials and how various guide-wave types interact with various types of damage such as delamination [37] and fiber breakage, especially fiber microbuckling that is observed when the laminate is loaded in uniaxial compression [38]. Two technical reports on aircraft damage tolerance requirements and aircraft structural integrity that may be useful to the reader/researcher can be found in references [39,40].…”
