A Bayesian framework for fatigue life prediction of composite laminates under co-existing matrix cracks and delamination
No full textThis paper proposes a particle filter-based Bayesian framework for damage prognosis of composite laminates exhibiting concurrent matrix cracks and delamination. Literature shows a number of applications of particle filtering for real-time prognosis of metallic structures and, recently, matrix crack density evolution in composites. The work presented here enhances the methodology proposed in previous papers by extending the Bayesian framework to multiple damage mechanisms, and validates the approach using damage progression data from notched cross-ply CFRP coupons subject to tension-tension fatigue. A multiple damage-mode model for the estimation of the strain energy release rate and the remaining stiffness of damaged laminates constitutes the core of the particle filtering algorithm, thus allowing the prognostic framework to extend for monitoring of simultaneous, coexisting damages. Also, the damage state can be evolved into the future enabling simulation of damage progression and prediction of remaining useful life of the composite material. The proposed prognostic unit successfully predicts damage growth and fatigue life of the laminate, and the results are critically discussed with respect to filtered estimation of damage progression and remaining life prediction
An investigation of strain energy release rate models for real-time prognosis of fiber-reinforced laminates
No full textTechnological advancements in real-time distributed sensing and processing for structural health monitoring systems have enabled exploration of the next frontier in structural health monitoring for in situ condition-based prediction of remaining life of damaged or aging structures. In that context, model-based prognostics methods have shown considerable promising results. These methods require that suitable damage progression models are available or be developed. Recent works have shown that energy release rate models work effectively for predicting material stiffness degradation based on matrix-cracking. However, since delamination and matrix-cracking damage modes are known to co-exist and fuel each other's progression, it is desirable to investigate extension of these models for multiple damage modes. To that end, this paper analyzes several multiple damage-mode models from composite modeling literature and assesses them against experimental data from run-to-failure aging experiments. These models aim to estimate and correlate strain energy release rate and the residual stiffness as a function of the damage extent. Model review in this work reports modeling behavior and mathematical complexity along with strengths and limitations of these models. This is expected to guide selection of suitable model for a more robust prognostic solution generalized for more realistic degradation scenarios

Aircraft hydraulic power system diagnostic, prognostics and health management
No full textThis Individual Research Project (IRP) is the extension research to the group design project (GDP) work which the author has participated in his Msc programme. The GDP objective is to complete the conceptual design of a 200-seat, flying wing civil airliner—FW-11. The next generation aircraft design demands higher reliability, safety and maintainability.
With the development of the vehicle hydraulic system technology, the equipment and systems become more and more complex, their reliability and maintenance become more difficult for designers, manufacturers and customers. To improve the mission reliability and reduce life cycle cost, there is strong demand for the application of health management technology into airframe system design.
In this research, the author introduced diagnostic, prognostic and health management (DPHM) concept into the aircraft hydraulic power system development. As a brand new technology, it is a challenge to apply the DPHM techniques to on-board system. Firstly, an assumed hydraulic power system was designed for FW-11 by the author and used as the case in his IRP research. Then the crucial components and key parameters needed to be monitored were obtained based on Function Hazard Analysis and Failure Modes Effects Analysis of this system. The writer compared a few diagnostic and prognostic methods in detail, and then selected suitable ones for a hydraulic power system. A diagnostic process was applied to the hydraulic power system using a Case-based reasoning (CBR) approach, whilst a hybrid prognostic method was suggested for the system. After that, a diagnostic, prognostic and health management (DPHM) architecture of the hydraulic power system was designed at system level based on the diagnostic and prognostic research. The whole research work provided a general and practical instruction for hydraulic system design by means of DPHM application
Dendrocellus Schmidt-Goebel 1846
No full textDendrocellus Schmidt-Goebel, 1846 Type species: Dendrocellus discolor Schmidt-Goebel, 1846 (= Desera nepalensis Hope, 1831)= Desera Hope, 1831 (nec Dejean, 1825) Type species: Desera nepalensis Hope, 1831 Bousquet (2002) and Liang et al. (2004) have correctly reconstructed the complex nomenclatorial history of this genus, reaching the conclusion that its valid generic name is Dendrocellus Schmidt-Goebel, 1846, instead of Desera Dejean, 1825, as it was frequently considered previously. We only observe that back in 1949 Jeannel already wrote: “Les Dendrocellus Schm. -Goeb. (type: discolor Schm. -Goeb.,= nepalensis Hope) sont généralement classés à tort sous le nom de Desera. … Malgré leurs ongles tarsaux pectinés, ils sont très voisins des Drypta s. str. ” (Jeannel, 1949). So, it seems the french author had already reached the same conclusions. This genus, recently revised by Liang & Kavanaugh (2007), contains 22 species occuring in Africa, Asia and Australia. Systematically it is extremely close to Drypta, differing only in its tarsal claws pectinate instead of smooth. The genitalic characters of both sexes are the same, the external resemblance among members of the two genera is sometimes puzzling and a few species of Dendrocellus show very slight tarsal pectination, sometimes leaving a doubt on their generic pertinence; only a comparative study of all the characters of the species belonging to the two genera will allow to decide whether they can be really maintained as separate genera. Already in 1968 Darlington observed: “ Desera differs from Drypta only in having pectinate tarsal claws. A modern revision of the species is needed to show whether both genera are really monophyletic and distinct” (Darlington, 1968, p. 218). The unique combination of characters distinguishing this genus from the others of the tribe is: pronotal bead absent or very rudimental (fig. 10); punctuation on head and pronotum dense, regular, the punctures usually well distinct from each other; pronotum very feebly constricted towards base; elytral microsculpture well developed; elytral pubescence dense, usually arranged in two-three more or less regular rows; scutellar pore constantly single; intervals flat or slightly convex; tarsal claws slender, more or less pectinate on inner side; two to five evident setae on outer side of stylomere (fig. 8).Published as part of Sciaky, Riccardo & Anichtchenko, Alexander, 2020, Taxonomic notes on the tribe Dryptini Bonelli, 1810 with description of a new genus and species from China (Coleoptera: Carabidae: Dryptini), pp. 522-530 in Zootaxa 4731 (4) on page 524, DOI: 10.11646/zootaxa.4731.4.5, http://zenodo.org/record/366198
William Goebel: The Politics of Wrath
No full textThe turbulent career of William Goebel (1856–1900), which culminated in assassination, marked an end-of-the-century struggle for political control of Kentucky. Although populism had become a strong force in the nation, the Louisville and Nashville Railroad and ex-Confederates still dominated the state and its Democratic party. Touting reforms and attaching the railroad monopoly, Goebel challenged this old order.
A Yankee in a state that fancied itself southern, Goebel had to depend on a strong organization to win votes. As “The Kenton King” he created a new style of politics. To some he was a progressive reformer; to others, a tyrannical machine boss. His drive for power and his enemies’ fierce opposition aroused violent political factionalism. Goebel’s fateful duel with a rival, his partisan election law, and his ruthless convention tactics led to the bitterly contested gubernatorial election of 1899 that resulted in his murder. Although the full truth about the murder was never revealed in nearly a decade of trials and the advent of progressive politics was long delayed in Kentucky, Goebel’s death did relieve the state’s political turmoil and induce some legal reforms. Using new sources and fresh perspectives, James C. Klotter portrays Goebel’s tumultuous era and discovers the real man within the obscurity of his conflicting images.
James C. Klotter is professor of history at Georgetown College and the state historian of Kentucky. He is the author or coauthor of several books, including A New History of Kentucky.
