Spring constants of filament-wound composite circular rings

Abstract: 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… Show more

“…Thus, Scowen and Hughes [2] introduced the 'sulcated spring' and was proved to be a very promising concept in non-linear spring response. Closed-form solutions of the diametrical, in-plane bendingshear and bending-torsional stiffnesses of mid-surface symmetry composite circular springs were derived by Tse et al [6] and verified by experiments. An analytical study using the energy method was followed by Akasaka et al [4] to evaluate the spring constants of elliptic composite springs.…”
