A review on design for manufacture of variable stiffness composite laminates (2016, background): “In many studies, the ply thickness is supposed to be constant for the optimisation of fibre angle orientations.(6,7,23,24) However, the buckling load for the physical specimens (plates manufactured with dry fibres) may not match the results from finite element analysis (FEA), when the thickness is c”
Tailoring for strength of composite steered-fibre panels with cutouts (2010, methodology): “A set of physically-based criteria developed at the NASA – Langley Research Centre (LaRC) is used in the analysis of first-ply failure behaviour of constant and variable-stiffness composite panels in the postbuckling regime, a method previously employed by the authors [19].”
A Theoretical Model to Study the Influence of Tow-drop Areas on the Stiffness and Strength of Variable-stiffness Laminates (2009, methodology): “This concept is shared by the research of Tatting [2], Gürdal [4], Jegley [5], Wu [6,7], Blom [10,11], and Lopes [8,9].”
Optimization of variable stiffness composites with embedded defects induced by Automated Fiber Placement (2014, background): “[15] investigated the first-ply failure load of a variable stiffness laminate.”
Improved aeroelastic tailoring using tow-steered composites (2013, background): “Analytical and experimental studies have shown that the buckling strength and post buckling-behaviour of VAT flat panels can be improved by redistributing the loads in a panel [15–23].”
Optimum stacking sequence design of composite materials Part II: Variable stiffness design (2010, background): “constant stiffness design have been demonstrated for different properties such as buckling capacity [38,91,1], elastic behaviour [28], stiffness [89], compressive buckling and first-plyfailure [63], maximum fundamental frequency [12] and postbuckling progressive damage [62].”
Multi-objective optimization of curvilinear fiber shapes for laminated composite plates by using NSGA-II (2013, methodology): “[1, 7-11] defined fiber shapes by the linear changes in fiber orientation angles to require locally desired material properties for plates and conical shells, and confirmed that such structures have superior mechanical properties compared with homogenous plates by research including experimental and”
