“…The non-linear load±de¯ection and stiVness characteristics of specially orthotropic, mid-surface symmetric, laminated circular rings under uniaxial tension and compression in the diametrical direction were also investigated. Large-de¯ection non-linear spring behaviour was obtained and veri®ed by experimental testing [7,8].…”

Closed-form solutions from complementary strain energy are derived for the spring stiffnesses of mid-surface symmetric, filament-wound, composite circular rings under unidirectional loading. A three-dimensional finite element analysis (FEA) including the effects of transverse shear has also been applied to study the problem. Four > 45° and four > 75° E-glass/epoxy composite rings of odd numbers of covers were tested. Comparisons of the results obtained from the two methods with experimental data are made and the results are found to be in good agreement. The FEA prediction of stiffness is always higher than the theoretical result. The relationships between the spring stiffnesses and the winding angles and geometry of the filament-wound composite ring are considered and discussed.

“…The use of nickel-titanium alloy wires in altering the spring rates at elevated temperatures in composite circular rings was also investigated (Wong et al 2004). Tse et al (1994) investigated the behavior of composite circular rings under uniaxial compression using the equivalent flexural rigidity approach. In another approach they investigated the stress and strain distributions of a mid-plane symmetric laminated circular ring under uniaxial loading Corresponding author, Professor, E-mail: elhajjar@uwm.edu Peng Yang, Stacy Van Dyke and Rani F.

An analytical and experimental investigation is performed into the mechanical behavior of carbon-fiber/epoxy woven coned annular disk springs. An analytical approach is presented for predicting the deformation behavior of disk springs of specially orthotropic laminates with arbitrary geometric parameters. In addition, an analytical methodology is proposed for obtaining the deformation behavior of a stack of disk springs. The methodology is capable of accounting for parallel and series arrangements for uniform and irregular stacks. Element and assembly experimental results are used to validate the proposed method showing how to achieve flexible spring rates at various deflections ranges. This manuscript also provides guidelines for design and validation of disk spring assemblies.

“…The approach presented in this paper is inspired by the ring approach [2][3][4][5][6]. This analytical solution measures the deflection of a circular sprig under stress, and also [7] presents an analytical solution of elliptic arches.…”
