Analysis of Tow-Placed, Variable-Stiffness Laminates
… which is composed of such plies will have stiffness properties which vary as a function of position. Previous work had modelled such variable-stiffness laminae by taking a reference fiber path and creating subsequent paths by shifting the reference path. This thesis introduces a method …

Finite element modelling and analysis of composite flywheel disk including effects of filament-winding mosaic pattern
… in fibre orientation angles which generate stiffness variations and composite laminates with such stiffness variations are called variable-stiffness laminates. Thus, varying fibre trajectories should be modelled accurately to incorporate the actual stiffness variations for FEA of …

Finite Element Modeling of Tow-Placed Variable-Stiffness Composite Laminates
… The result is a laminate with spatially varying stiffness and response. This manufacturing method can also result in overlap regions between adjacent tow paths. In previous research, a closed-form solution was developed to determine the response of these variable-stiffness laminates, but the …

Optimal Design of Variable-Stiffness Fiber-Reinforced Composites Using Cellular Automata
… In the traditional design of composite laminates, fiber orientation angles are constant for each layer and are usually limited to 0, 90, and ±45 degrees. To fully benefit from the directional properties of composite laminates, such limitations have to be removed. The concept of …
