Defect layer method to capture effect of gaps and overlaps in variable stiffness laminates made by Automated Fiber Placement (2013, background): “AFP allows the manufacture of variable stiffness laminates with curvilinear fiber paths which offer a more favorable stress distribution and an improved structural performance [2–6].”
Surrogate-based multi-objective optimization of a composite laminate with curvilinear fibers (2012, background): “With the latter, the fibers are allowed to follow curvilinear paths within the plane of the laminates, thereby giving the freedom to tailor the properties in directions that are favorable to carry the load within the laminate [1].”
A review on the mechanical behaviour of curvilinear fibre composite laminated panels (2014, background): “Due to the large number of possibilities offered by curvilinear fibres, optimisation procedures are obviously interesting in VSCL design.(105,106) In Ghiasi et al.”
A review on design for manufacture of variable stiffness composite laminates (2016, background): “Ensuring continuity along the composite structure is one of the main issues related to variable stiffness design.(27) For instance, using a finite element method (FEM) for optimising fibre orientations is likely to result in discontinuities between elements if constraints are not imposed.”
Strength and mass optimisation of variable-stiffness composites in the polar parameters space (2021, methodology): “Traditionally, the design of VSCLs has been carried out by optimising the fibres-paths within each ply, by using the so-called direct approach (Ghiasi et al. 2010).”
Framework for the Buckling Optimization of Variable-Angle Tow Composite Plates (2015, methodology): “[6] presented a thorough review of different optimization techniques for the design of variable stiffness composite plates, in which it was concluded that the multilevel optimization method is recommended due to its highly computational efficiency.”
Reliability in composites – a selective review and survey of current development (2012, methodology): “Almeida and Awruch [106] have recently provided a variable codification method for composite applications with special emphasis in composite structures optimization and in [70,71] for those cases when the stacking sequence is also involved into the problem definition.”
