Fusion-based damage diagnostics for stiffened composite panels

چکیده
Conducting damage diagnostics on stiffened panels is commonly performed using a single SHM technique. However, each technique has both its strengths and limitations. Rather than straining the expansion of techniques going beyond their intrinsic capacities, these limitations should instead be considered in application. In this work, we propose novel fusion-based methodology between data from two order to surpass capabilities The aim show that by considering fusion, synergy can obtained, resulting comprehensive assessment, not possible For purpose, three single-stiffener carbon–epoxy were subjected fatigue compression after impact tests. Two monitored growth under applied loads: acoustic emission distributed fiber optic strain sensing. Four sensors placed panel, thereby allowing for detection, localization, type identification (delamination), severity assessment. optical fibers adhered stiffener feet’ surface, measurements used disbond (stiffness degradation growth), Different fusion are presented integrate data. detection hybrid health indicator obtained feature-level while complementary cooperative diagnostic results developed localization identification. We up until final failure, performing simultaneous assessment all four levels. manner, demonstrate proposing approach toward composite structures, capacity utilized, leading synergistic effects diagnostics.

Failure Prediction of Stringer Stiffened Composite Panels with Impact Damage under Uniaxial Compression
The in-plane compressive behaviour of thin-skin stiffened composite panels with a stress concentrator in the form of an open hole or low velocity impact damage is examined analytically. A fracture mechanics model, developed initially to predict notched compressive strength, was applied to estimate the compression-after-impact strength of a stiffened panel; in the analysis the impact damage is r...
متن کاملDesign optimization of stiffened composite panels with buckling and damage tolerance constraints
The design of stiffened, composite wing panels must satisfy a range of requirements related to performance, economy and safety. In particular, the design must be damage tolerant to satisfy a number of different performance requirements for various states of damage. To obtain an optimum configuration that satisfies these requirements simultaneously, optimization code PANOPT was extended with a m...
متن کاملOptimization of Composite, Stiffened, Imperfect Panels under Combined Loads for Service in the Postbuckling Regime
Local buckling and postbuckling of panels stiffened by stringers and rings and subjected to combined in-plane loads is explored with the use of a single module model that consists of one stringer and a width of panel skin equal to the stringer spacing. The cross-section of the skin-stringer module is discretized and the displacement field is assumed to vary trigonometrically in the axial direct...
